You can solder from the top, bottom, or both. There are two 1N914 diodes used in the output stage, and one 1N4001 used to protect the relay coil. Hairball Audio | Elements | Elements Share Reply Quote 16th July 2014 #2 hasbeen Lives for gear 1 Review written 15 years Thanks for the heads up! Choosing to build your own piece of gear is a rewarding and great learning experience. H = Hardware Electrolytic capacitor types found in the Elements series shown above. Look close! They are hard to make look pretty, so just get them in and soldered well. The images that follow cover the types found in Elements; your build may or may not have all these types. COPPER NOTE: C501 is tantalum and polarized however, the pads on the PCB do not indicate polarity. 600 = Output Amplification Stage ("OUTPUT", "TERM"), A = Assembly In this case, the pad closest to the rear edge card connector is positive and the pad closest to the front panel is negative. To make it easy for you, the PCB silk-screen matches the package of the transistors. Yes, you can with our step by step build guides. HAIRBALL Audio ELEMENTS BRONZE $ 790.00 CAD $ 759.00 CAD Bronze Colored. This should be just below the bump-out on the leads. 12 talking about this. It includes the components used for your particular build. The videos are lengthy at about 25 minutes each, but they are well worth watching. This footprint is for silver builders who wish to use an DIP-8 IC rather than a discrete op-amp. Now you can wire the output. 200 = Direct Input Relay ("DI RELAY") It slowly dims when deactivated to let you know when the phantom cap is fully discharged. Too much solder can wick up into the socket making it impossible to insert the op-amp later. These protect the +16 VDC, -16VDC, and +48VDC rail from exceeding 100mA which should never happen in a properly functioning Elements mic pre. VR = Variable Resistor (potentiometer), Populating the Printed Circuit Board (PCB). Patience is key to the success of your build. Resistors are not polarized. 500 = Input Amplification Stage ("INPUT", "GAIN") For nearly a decade Hairball Audio has partnered with talented PCB designer Mako Natsume. You may have opted for the Grayhill option for either the gain, output, or both. Remember less is more when it comes to solder. For the output pot all of the positions get a 1KΩ pot. There are two DIP-8 footprints on the PCB. # Repost @stevensoundengineer with @get_repost Can't wait to build this 1176 clone frome @hairballaudio ! In addition to the BOM and components, you'll want to grab your soldering iron, solder, digital multimeter (DMM), lead trimmers, and a lead forming tool or needle-nose pliers. Patience Last, add the knobs. Q = Transistor Place the sockets in the socket pads. Learn how to use and connect your Hairball Audio microphone preamplifier to your interface. Now slide the panel on and secure it in place with the DI nut. The lead forming tool shown below is Mouser part 5166-801, but a pair a needle-nose pliers will work just as well. They are Copper (pictured) Gold and Bronze We offer these "kits" as fully assembled and working devices. Build Maps The Gold and Bronze have PCB lead transformers and the Copper has an input transformer with wire leads. Do you want to have a failed build and a huge headache? hairballaudio.com/eevblog-solder-tutorials. Now you can mount the enclosed panels using the remaining 3/16" #4-40 screws. Now solder the lead into place confirming the leads are inserted into the proper pads. I know my resistor color band codes, but I’ve checked this 150KΩ resistor anyway. Move through each step carefully, take pride in your build. Place the component in the PCB so the ridge and line match up. Web design by efelle creative. We got your back! All the parts listed in your BOM will be included in your kit. R5: 412Ω Yes, you can with our step by step build guides. Copyright 2020 - Hairball Audio. That's ok as long as the solder joints are good. Leave it empty! Soldering Guide These are not polarized and all three are identical. To avoid damage, grip it using the PCB sides rather than a component. Top soldering op-amp pins shown above. Axial lead capacitors have leads coming from either side of the cap. Your IC will either have the same semicircle or a dot. Once you begin stuffing the PCB you will have lots of cut component leads to make any shorts. Even I learned a few things. Too easy! Here is a rear view of the assembly. The film and ceramic capacitors are non-polarized and can be inserted in either direction. A – 1176 – Compressor $ 1,050.00 CAD $ 990.00 You can also slide the tooth washer that came with the pot on to the shaft. This is their first product designed from scratch. The attack and release network, previously the trickiest wiring in the build, is now on its own small PCB that easily mounts to the main board with the supplied connectors. You'll need to play with it a little to make sure the Grayhill switch and washer is centered. Finally, look at the bracket and identify the short leg. Hairball Audio, LLC currently offers repairs on kit builds. Short and Omits Transformers: Box contains the input and output transformers for you build. The FET/RACK compressor series is no exception. Named Lola, after the founder's dog, Hairball Hairball Audio 1176, Universal Audio 1176, Purple Audio, Warm Audio, etc, are great options. It's the part where your module finally comes together. Axial lead film cap with leads bent. Our focus was not to manufacture products overseas in places such as China to keep our costs low. There are three, and though two look the same, they're not! The orientation of the mounting holes will show you which way they are installed. I use high quality Kester solder and build these by hand. There are three push-button switches included with your kit. Our time for repair work is offered at a flat-rate fee. You'll rest easy later on. By default it's set to the XLR mic input. The videos can be seen by visiting: The bottom is flush to the PCB edge. Silver switches have a tendency to tarnish and degrade over time if they are not DC biased, meaning they have DC potential across them. The result was dubbed the Raindog op-amp. KSA1220AYS (Q600) is a PNP transistor and KSC2690AYS (Q601) is an NPN. Hairball Audiobooks is a project where productions of dramatized readings are produced. What's very cool is that when they trip, all you need to do to reset them is power cycle your rack. This indicates how the diode should be inserted. If you have an older kit with the shaft reducer,  the Grayhill is slightly more complicated. Once you try, it starts to seem kind of difficult. airball Audio is the Seattle Company responsible for bringing us key elements for the DIY version of the 1176 Blue Stripe [Tape Op #84]. R3: 1.74KΩ Use your eye for alignment. But the 10 talking about this. Simply align it with the sockets and press it firmly into place. Our custom 2U enclosure was designed for Hairball Audio and is made in Seattle, USA from 18 gauge steel. You'll need to pinch and wiggle them a little to get them in. There are several great options of 1176s currently in production. They are bent and soldered like resistors, however, there is one major difference: DIODES ARE POLARIZED DEVICES. Soldering the pots in place is simple. Grayhill gain kit is shown above. The hollow end should be facing up, this hollow shaft accepts the op-amp pins. D = Diode (rectifier, signal, or Light Emitting) Note you may need to wiggle the LED into the LED hole. If you look at the silkscreen you'll see that the end of the relay closest to the front panel has semi-circle. We decided to go with the Hairball Audio 1176 Revision D for a few reasons. Heavy. Take your time (really, please TAKE YOUR TIME), the extra time now can save you hours or days of troubleshooting. Start by identifying the negative lead and the negative PCB pad. Now that you have a bunch cut resistor leads, go ahead and solder in those shorts! You'll want to combine your base kit and specific kit as Note: When reading the BOM, R is ohms and K is kilo-ohms and they are placed where the decimal would be. However, we’ve decided to approach this differently. Start by soldering one long header lead so you can adjust the positioning by reheating that lead. The socket is a large part that will need about 5 seconds of heating time to get good flow. These kits include only the highest quality USA made custom enclosure and transformers. Copper is the sound that every engineer and manufacturer chases. Their positive lead is marked with a "+" and a line pointing to it. There are a few different ways to solder the op-amp sockets. This might be your first time doing this so it may not look pretty or sit flush. These little awesome dudes will protect your build, rack, and other modules from catastrophe. Keep the shaft adaptor and washer in a safe place for now (like on the switch). HAIRBALL Audio Elements Or $ 790.00 CAD $ 759.00 CAD L’Or est basé sur l’ampli-op classique Jensen 990. Do not apply a short or any other component. Soldering WELL is one of those things that seems easy until you try it. It must be installed correctly and in the correct location. On your diode you will notice one lead is marked with a line. The rate includes full testing and calibration (if required Capacitors have two lead style: axial and radial. Once you are happy it is flush and square, solder the other two leads into place and trim the leads at the front of the PCB. We offer flat rate repair on all of our DIY builds if you get stuck. Rushing through the build and paying little attention to the instructions will result you in being sloppy with your soldering and assembly. If you have the Grayhill option and you have 1/4" holes, you'll need to add the supplied washer to the front and secure it with the Grayhill nut. Title hba-elements-pcb-v1-3_schematic --- production.brd Created Date 9/21/2014 5:45:48 PM Web design by efelle creative. Again you'll want to trim access lead before soldering. It's also a BJT transistor and inserting it correctly is as easy as lining up the D shaped transistor with the D shape on the silkscreen. Tread a 1/4" standoff onto this end through the bottom. The new PCB design is a nod to the classic layout. This is my review of the Hairball Gold pre. 11 räägivad sellest. Technical Support Hairball Audio kits are sold without support. Click the appropriate link below to access the BOM and build map for your kit. Diodes are next. You'll need them for the final assembly. Let's start with resistors since they are small and account for many of the on-board components. Rather than trying to explain it to you, I went online, to find the best video tutorial I could. This video will walk you through the process. We are in the process of moving from 1/4" to 1/8" gain and output holes. R2: 3.9KΩ Tools Modern recreations from larger transformer winders tend to focus on improving specifications, which washes out the original character and tone that made these compressors so famous. The Base and Gold kits have a few Nichicon VP series capacitors which are bi-polar/non-polar and can be inserted in either direction. To avoid having this connection short to ground through the module enclosure, you should cover it with electrical tape or a small piece of shrink wrap.

Copyright 2020 - Hairball Audio. # Repost @stevensoundengineer with @get_repost Can't wait to build this 1176 clone frome @ The kits includes the following boxes: Base Kit:  Includes all common components required in the circuit regardless of which preamp you're building. The customer pays for all replacement parts and return shipping. The Hairball Audio Elements series of DIY mic preamps provides several new takes on a classic preamp topology: transformer-coupled I/O, and a single discrete op-amp for gain. The long lead is positive and the flat side of the LED ridge is aligned with the negative lead. For the gain pot, the value placements are: R1: 12.7KΩ Shorts on a gold PCB shown above. The LED bottom ridge is just over the edge and ready for soldering and trimming. After, proceed to the Troubleshooting Guide for your specific product. Be sure not to apply too much pressure to the socket or it may lift causing it to sit slanted on the board. Then finally you figure it out and it seems easy again. The IC in your kit is used as a DI buffer and is installed in U300. Elements Specific:  This box is labeled either Gold, Copper, or Bronze. The phantom switch has significant DC bias and can be switched with silver with no risk of long term tarnish. First things first! We could go a few different directions at this point, but let's move to transistors. Be patient, let it heat and go easy on the solder. Test each resistor with your DMM Ω setting before soldering it in place. The default output option when purchasing the kit is a potentiometer and the input is a Grayhill. If you like, you can pop the caps on now, the pad and phase switches get black caps, and the +48 switch gets the red cap. Film capacitor types found in the Elements series shown above. C = Capacitor (assorted) Two #4-40 screws hold the copper transformer in place. The partnership, based on a passion for quality design, has yielded some of the best DIY projects on the market today. There are 3 diodes used in the Elements series and they are part of the base kit used in all revisions. You need to cut these short and solder them directly together. DIY Audio Kits and Parts Love hearing how people got hooked on DIY! Dave’s a wacky cat, but so are most guys who inhale lead all day. Staying within the same company’s product line, though, I have finished two other kits I purchased from Hairball Audio: a pair of their Elements Bronze series preamps. Next, simply follow the pad/wire color coding to solder the wires into place. The floating PCB allows top and bottom PCB access for ease of install and troubleshooting. Two are gold and one is silver. For these TO-220 transistors, you'll notice the silkscreen has a trapezoidal shape with a line on the wider end. Our transformers, custom designed by Ed Anderson, are meticulous recreations of the original UTC 0-12 input, 5002 output transformer, and 11754 power transformer. This would create a short and take the cap out of the circuit. 104 Followers. Components are generally stuffed from shortest to tallest for easiest assembly. For the Grayhill, you may or may not want to place the supplied rubber spacer behind the faceplate. The Common Build Errors and Troubleshooting Techniques article is the best place to start. British.Hairball Elements Copper is our take on the classic British console sound.Copper is the sound every engineer and manufacturer chases. The kit includes an integrated circuit (IC) that has 8 leads, 4 on either side. These are bipolar junction transistors (BJTs) and they have a collector, an emitter, and a base. and stop at the point where you think bending it forward will cause the ridge to extend just past the edge of the PCB. The Axicom 24V relay controls whether your pre is using the XLR mic input on the rear of the rack or the 1/4 inch unbalanced instrument DI input. Most of the electrolytic and tantalum caps we'll be using are polarized. Component values follow these designations: 100 = Power Supply Distribution and Decoupling ("PWR") Installing the op-amp is easy. R503 is a 68K resistor that has a 100pF ceramic disc capacitor in parallel with it. You can identify them by looking at the rear of the pot where their values are identified. The output transformers all get installed similarly. Grab the two 1" #4-40 screws, #4 flat washers, toothed washers, and #4 nuts from the hardware kit. R4: 845Ω S = Switch Determine whether curling the negative lead or positive lead will make the cap fit best with the components around. We build them and test them here @thepandastudios. You can easily do this with a cut resistor leg. For the pots this is simple. JP = Jumper Example: 39R = 39Ω 3R9 = 3.9Ω 15K = 15K Ω 1K5 = 1.5KΩ. DOA = Discrete Op Amp For Bronze, C503 is left empty. Hardware: Box includes all of the front panel parts and screws. If you have a good connection on the top side there is no need to solder the bottom side. Hairball Audio Elements Gold When you buy products through links across our site, we may earn an affiliate commission. The last transistor is a TO-92 package which is D shaped and it controls the DI relay. The cap is also not polarized and can be inserted either way. For Gold and Copper, we'll only be using one pad per label. Personally, I like to begin by inserting the op-amp sockets. FET/RACK complete kits feature only the best board-level passive components carefully selected by ear to impart all of the original color and tone of their original counterparts. Main focus is on science fiction, post-apocalyptic, action/suspense, epic fantasy elements and sometimes documen. Make sure you use both the basic kit and your element kit specific components. On the PCB the positive pad is always square. Notice the PCB is flush and at 90 degrees. Short means the designated component must be shorted by directly connecting its pads. Now place the Grayhill assembly on the PCB and mount the long side to the main PCB using the second screw 4-40 screw. Rather, our focus is to provide only the best parts available and to never compromise. Classic. The most important part is that you get good solder flow around the entire socket and PCB pad connection. Be careful not to bend the leads too close to the cap body as it can be damaged. They're labeled. HAIRBALL Audio ELEMENTS COPPER $ 790.00 CAD $ 759.00 CAD Hairball Elements Copper is our take on the classic British console sound. This line identifies the negative or cathode lead. PDF Bill of Materials F = Fuse (PTC resettable) HAIRBALL Audio Elements Cuivre $ 790.00 CAD $ 759.00 CAD Hairball Elements Cuivre est une version du son de console britannique classique. There are two large rectangular TO-220 package transistors. Mount it flush to the PCB and solder it into place. Some kits have axial lead film caps. Go ahead and solder in the shorts as you cut off component legs. Next solder the 3 pin header in place on the rear of the PCB with the longer lead side. They are located in the base kit box. For Bronze, you use both. For this reason, we'll use the two gold switches on the phase and pad which are "dry". The short leg mounts to the Grayhill PCB using one of the 4-40 screws. As much as you want that cool new piece of gear up and running NOW, take your time and make sure to take breaks. The Bronze input has the dot on the bottom and the Gold has it on top. Read More Parallel Compression 101 Learn how to route and add parallel compression to your mixes. Hairball Audio in Seattle is the same company behind a number of kits I’ve already added to our rack — the four FET/500 1176 compressors, and the two Elements Bronze preamps I’ve told you about here on the blog. I like to tilt my PanaVise so it’s parallel to my table surface with the silkscreen side up. While the other preamps land in well-known categories, Bronze is definitely its own beast. Set the pot shafts to full CCW and align the knobs to the first dot. The sockets must be inserted from the top side (silkscreen side) of the PCB. When you start to see that solder flow, apply some solder to the opposite side of the pad while keeping your iron tip in the original location. Don't forget the middle pin! Discard the toothed washer. A sloppy build, even if it's working, won’t give you the same sense of satisfaction as that of a good, clean, and neat build. It needs to sit behind the front panel. Place a flat washer on a screw and insert it into the top (wire side) on the transformer. Your build may or may not have these shorts, refer to the BOM. Hairball consulted with Eisen Audio to adapt the LA-3A output amp for the 2520 format. Tighten both set screws with a 1/16 hex key. Now push the LED forward. They are used in addition to the base kit. Copper will have a purple and blue lead remaining. Tantalum caps (copper only) are polarized as well. 400 = Preamp Input Circuitry ("48V", "POLARITY", "PAD") Place a toothed washer over the male end of a 1" standoff and insert it into one of the 4 PCB moaning holes. Pretty easy! You should also reference the PDF BOM below. In summer of 2016 we released the next generation FET/RACK. The footprint for U300 has a semicircle on one end. You can certainly use silver, and your switches may be fine and clean for years however, we wanted the elements series to last a long time without requiring service. Bronze is an amazing, colored, and unique pre. These leads are the Anode (+) and Cathode (-). Mount the transformer so the wires face the pads (for the bronze this is either way) and secure it in place with the lock washer and a nut at the bottom. The partnership, based on a passion for quality design, has yielded some of the best DIY projects on the market today. The authenticity and sound of the new FET/RACK is unparalleled. Hairball Audio prides itself in creating the highest quality kits, while keeping design elegant and simple. If you have the bracket right, the Grayhill PCB will sit flush with the main PCB at a 90-degree angle. You can see the top has ridges and the pad is square this indicates that they are both positives. Lead forming tool and angle cutters shown above. With that in mind, work continues on the other three Hairball Audio/MNATS FET/500 1176 clones I wrote about in my last post.
