Get yer 1176 here!

by Chris Randall
 

Building your own high-end gear is always something I recommend here at Analog Industries, and I attempt to bring you the easier-to-build stuff when I come across it. In that light, this site may be of interest to you. One of the many 1176 clones available as DIY. This one, like the last one I pointed out, has some mods, and has departed from its Gyraf roots a bit.


There are two reasons I point this one in particular out: (a) the circuit boards are only $20, and (b) the web page has _very_ thorough descriptions of the why and wherefor of the process. Thus, while it is a relatively simple build as such things go, you can actually learn about what's going on in the process, rather than just soldering components to a board. The expensive parts are the iron and the VU meter, as always. You're looking at about a $400 to $500 cost-to-build here, depending on the components you go with, but of the 1176 projects I've come across, this one seems to be the best way to go.

I'm 90% of my way through one of these mnats/Gyraf 1176's. I think my cost was closer to $300, which is better than the $1800 I saw for the UA copy at GC. I've already built up an API 312 mic pre and the sound is astonishing. A few DIY hints:

- Buy the circuit boards. I bought all of the materials to etch my own boards, but the transparency printed at 95% by mistake. (It was Acrobat helpfully shrinking the A4 down to US Letter.) I didn't figure out the mistake until I was soldering in the last few pieces, and by that time it was too late. I ended up throwing the board away and starting from scratch.
- You can get sample ICs from TI.com. That can save you a few bucks.
- Transformers sound like nothing else. You've gotta have some transformer-balanced stuff in your studio.
- Measure each resistor before you put it in the board. Take breaks. Don't try to build the board in one sitting.
- The hardest part is the metalwork, especially drilling and filing the rectangle for the meter to poke through. You can buy engraved front panels from Schaffer, or roll your own and suffer the cuts and rubdown letters. (My cut still hasn't healed.)

My plan is to have a tube U47/67 mic, API mic pre and 1176 compressor as a signal chain, all home-built.

Still looks good even now, bit scared of building my own stuff but maybe something older like this would be the way to go. Rich @ link [piano-tutorial.or...]">link [piano-tutorial.or...]
