Hi. Just finished this project and i am having problems with r76. Before it, i have audio probe and tested the 4.40 ac volts as per calibration. Right after it, audio is almost lost and ac volts drops down to few millivolts. Any clues?

Did you use original 3080s, or fake ones from, lets say, aliexpress?
I'd start with removing 3080 and other active components and measuring the results. 3080 could be faulty, Q1 could be faulty and so on.

So what made you think that compressor is working okay if there is almost no signal after r76?)swt wrote:Thanks plush. Strange is that compressor is working ok. I have audio probe til one leg of r76. Then it drops to almost nothing . If i take the comp ics out...still the same.
Check c36, and Q1.
