At this point you can start to stuff the main PCB. It’s a really good idea to stuff the power section of the board first and also hoookup the power transformer so that you can test your power rails and make sure you don’t blow the board. This will also save some heartache later on if things don’t work and you have to start troubleshooting…… First I hookup the power transformer: Next I stuff the power section of the PCB ONLY: Then once you have checked your power rails, you can stuff the rest of the board: ….and then mount the PCB in the chassis: Next will be the ratio board and main...
Okay so the next stage is to get the switch units connected up. The Hairball audio compressor kit comes with 2 switch units, one for the meter switches and one for the ratios. The pack also comes with 2 mini PCBs for the switch assembly. Solder on the required resistors and then solder in the switches themselves as per the photos below: The next stage that I do as this point os to wire in the XLR input and output and also hook up the input transformer and hook that up ready for the main PCB: Next we can solder the main input section of the PCB and also hook up the power transformer and test that it’s working before populating the rest of the PCB……....
So once you’ve unpacked all the parts to your new 1176 clone what next?? The first thing I do is to assemble the sides, front and back of the chassis as per the picture below: It’s imperative to test the chassis for continuity at this point as well, to make sure that all sides of the unit make contact so that it will earth properly. I use a continuity tester with an audible ‘beep’ and test at various points. You may need to scrape off some paintwork at the screw holes to make sure there is adequate contact. The next things to do is to fit the VU meter, the IEC socket and the power transformer. I put these on first as the first stage in the PCB build will be the power stage to check that’s right before stuffing the rest of the board so it’s handy to have the power stage ready. I only loosely fit the power transformer as you will need to move this around as and when you start wiring up but it helps to start getting everything in place. I also add the VU meter at this stage as it’s really fiddly to fit last when the switch PCBs are mounted. I also fit the “0” adjust pot now as well. See pictures below. The last thing I do at this stage is to mount the output transformer on the chassis. This is so that the PCB gets mounted at the right position in the case to facilitate wiring up without having to extend the output wires etc. That’s it for now. The...
I love 1176 compressors. So much so that I have already built 2 Blackface Revision D 1176 clones from Hairball Audio Now I will document here the new build of my Revision A Silverface 1176. First – unpacking everything!! This shot show the box plates and all the bags you get direct from Mouser – bags full of capacitors, resistors, diodes and transistors. This may look a little daunting but there is nothing more rewarding than creating your own hardware. Hairball Audio have a full step-by-step process on their website which makes the whole process way easier than it would be ordinarily. Remember – I had never done anything like this before and built 2 working units so anyone can do it! Check back for progress!...
Adrian, thank you for a great day and a half of recording finishing last Wednesday. Having been together as a group back in the 60s and now getting together 50 years on to record was a bit nerve racking but you made the thing so much easier with your professional advice and guidance. You've got a great set up and since we had Rog playing flute and drums [for some reason not at the same time!] the layering down of the instruments went really well. We had a great time and ended up with a CD and lots of happy memories. Martin living in France doesn't make it easy but we have all vowed to be back with something completely different for you to cut to disc. Thanks again and see you soon. Sam, Andy, Roger and Martin of Old Lemons fame.read more
This is a relaxed studio in a lovely location near the beautiful town of Saffron Walden. Adrian is a great sound guy, he listens and responds and adds enthusiasm to the day.
Top recordings with the best equipment for a great price ... highly recommended ��read more
Having recorded at Threecircles several times, there's good reason why I keep going back... with such high end equipment, Ade's expertise and competitive pricing there's no need to go anywhere else!!read more
I first met Ade when a charity band event needed a sound technician and PA rig at short notice, he provided top notch sound for the event and also offered a very well priced live recording, which he would go away and mix at Threecircles Studio. The results were brilliant, I have never heard myself recorded live so well and the mixing was fantastic too.
As a result, one of my bands then used Threecircles services again, this time at the studio to record a track for promotional purposes. We had a great time and were really happy with the results! Would highly recommend for both studio work and live sound.read more
Truly professional attitude and highly capable. Recommending these guys for studio work as well as live sound... Cheers guys, appreciate the extra effort you put in,making us sound truly amazing. 5 stars : )read more
Ade at 3C is a true hero. Aside from having professional equipment, incredible understanding and knowledge of music production and a brilliant studio - he is a real genuine man.
If I could I'd give this studio 6*, Ade recently recorded a single for my band completely for free because he knew we were doing it for charity.read more
Great recording facility! I've recorded at Threecircles twice now and enjoyed both sessions a lot, Ade is great to work with and has an set up of equipment and can produce excellent sound, and charges at a reasonable rate also! And the coffee is also a huge plus! ;)read more
