Have a pretty much complete kit for building Heikki's Transformerless Vari Mu Compressor
https://groupdiy.com/threads/transformerless-vari-mu-compressor-build-thread.78043/Nice quality parts. Black boards.
Just need wiring and case/face plate... Maybe standoffs for power supply board.
The sidechains are for the potentiometer version. I can see if I have extra stepped sidechain boards but you'd have to get all of the resistors and switches.
I think the parts included reflect the option of:
"If ability to drive 600 ohm loads is needed, replace caps C29, C30, C31 and C32 with jumpers. If ability to drive +26 dBu level to 600 ohm load is needed, replace resistors R39, R40, R41 and R42 with 1 ohm resistors."
But may have both options of regular vs above mod parts. Too lazy to look through.
Includes (2) Lorin stepped switches already assembled for the 10k input gains.
(4) Really nice matched 6SKGTY tubes (can deduct $50) if you don't want them
A kodak brick power supply with plenty of juice.. and it has short circuit protection....
I've gone through the bom a couple of times in the past so I feel pretty confident this will get you all the way through a build apart from what was mentioned.
Incredible compressor and very easy to follow build instructions .
$350.00 with Priority Shipping to continental US included.
Not sure what international would cost. Probably an extra $20-$30 US
Pretty firm on the price. Some of the parts aren't cheap and putting the kit (labeled) together takes time....
SOLD
I do still have some sets of vari mu boards left too btw. Very nice sets of blue with stepped sidechain option.... $100 a set shipped Priority to continental US
Also Have some of Heikki's Dual compressor boards with the diode limiter/ vari mu comp together...
