Anyone successfully build one yet with the thinner boards, I tried 2 now and all i get is a clean sound on flange mode and a slightly distorted sound when on matrix mode. this is happening on both boards.
Two builds same problem - what I would look at is if you are getting signal into and out of the MN3007 first. Audio probe pin3 for input and either pin7 or 8 for the output.
Got the old audio probe out. Signal on the input nothing on pin 7 or 8 so does that mean I have a dodgy BBD?

It could, but don't give up on it quite yet. How are your voltages on the BBD? I assume you have tried adjusting the clock and bias trims, correct? Did you make any subs on the build? And, where did you get your MN3007 from?
smallbear. Just noticed i have a 22k instead of the 24k at R23, will that be the problem.

Nope, that wouldn't affect it.

FWIW I've built two of the thin boards, they both work perfectly.
