Madbean's Current Lover - works but not quite as wished..

[Longer713]

Hello everyone!

I'm in big need to debug my Current Lover builds. Yes, I have 3 boards in progress and none of them works properly. I mean that before calibration I do get a clean signal (which is good) but during calibration sometimes I reach nasty clock clicking noise or very poor flanging (practicaly no jet flanging at all) comparing to what you can find on YouTube. I made a run through every single resistor and cap, tried to swap ICs and I'm kinda hopeless.



Here are my voltages:

And the PCB itself:

Is there anybody able to debud this board? Can it be faulty MN3007 chip?
Thank you soooo much in advance

Voltages look okay and if you're getting any sort of flanging the BBDs are fine.

I'd look for a wrong value, if something was mislabelled or mixed up in your parts bin that'd explain why it affected 3 builds.

Speaking about wrong value I had a problem with R32. I couldn't find 62k resistor so I can choose between 56k or 68k. Does this resistor have a big impact on overall circuit? I can see that it's close to Vc which goes to Clock trimmer and later MN3007..

All other parts are according to spec, I've checked them few times each one of them.
