heaveno again, I tried making this amplifier work again. I replaced some parts and looked over everything again once more. I really cannot find the fault here. I tried filming the amplifier with a thermal camera, and BR1 and BR4 are running really hot. None of the resistors or silicone in the middle seems to heat up, except E29 and R29.
Does this help at all? Any other input on what I could try? I really want this thing running.

I've completed the QRV-08 a few months ago and it has playing happily ever since. You weren't kidding when you said it reveals poor recordings. I'll post a picture when I get around to taking one.
I've found the standard gain of 4 to be too high with an AMB gamma 3 and a set of HD650s. Which resistors should I change to reduce the gain, and what values would you recommend for a gain of 2 or 1 respectively?
