Hi Nanakos.
I am sorry to hear that one of the channels malfunctioned. I am happy to help. You mentioned one of the channels played well and one had a problem. What kind of problem? Is it the same channel that failed? Please upload a few pictures if possible.
Hello everyone.
I am sorry for my absence. While even on a bad day I tend to sit at the PC to check the forum but for the time starting from late-April and mid-May I have been taken due to some serious family health issue and subsequently an untimely tragedy to cope with. It took some time to get off the depression. Now feeling much better and able to concentrate, so here I am.
Thanks for your patience.

The small heatsinks are needed only for Q25/26. As mentioned in the setup guide the other four medium transistors do not need heatsinking.
Extremely sorry to to hear Shaan. You take care. Family comes first and I think the rest can wait. Let us know if we can be of any help while you fully recover.
I am very sorry for your family problem. I hope the future is better.
The board is damaged and I have to make a new one. The problem was that was not increasing bias... I changed everything but nothing happened. The offset reset normally and the only difference in the measurements with the other board was that r31 r31 had 1.7k...... in the good only 0.2k. I also can't measure mV in the resistances you give in the instructions. I will need a new board immediately...
