Please take another somewhat larger and better illuminated picture of everything you have in that chassis and explain what you have there.
What I don't understand is why you have so many heatsinks there.
What are you using as a power amp and speakers?
There are pre-amp , tube simulation , SMPS and class D amp. But I think classD amp does not work well for this application. I have to go back to AB amp.
And for speaker it is normal PA type,15" .
I have just reduce the gain of first OP-amp (Reversed circuit) . And leave the last OP-amp of tube simulation as buffer. So it seem OK for me now.
