I will double check that. What I did was fitting a heat shrink tube to the screws, n that had been checked for couple times before I turn the power on, but no harm to check one more time.

If you change the gain, you also change the feedback.
That usually requires a change in the compensation.

Thanks for reply.
Can somebody help - what nominals of compensation elements (R11 - C7, R8 - C6) must use for gain 32dB?

Talking It's up running

Amp was running stable at 15mV for about an hour last night. It drifted a bit but can easily adjust them back to 15mV after 20 minutes. Temperature on my heatsink was only 28C. I thought I could run them a bit hotter so to test the sound is better or.....
There were -15mV and -9.5mV at output. Don't know if I have to make any correction to this issue.
Have to put up a protector, so I could taste the good sound.

Congrats! DC at your outputs are acceptable, I even have 50mV on mine and it's fine.

So, what did you do to solve your bias problem?
