First thing, the long white wire that you have running directly from the bulk capacitor bus bar lug to the copper plate under the input jacks. cut it somewhere around the middle of the control board, strip the end attached to the bulk capacitor lug and terminate this stripped end into the LEFT...

Please unlace your ty wraps going into the control board and post new pics so we can see what you have going on. I am unsure what you are doing with that white ground wire...

Pictures would help us help you

Your offset should be around 1 millivolt (0.001V), not 700 millivolts (0.700) 0.7V will slowly trip the DCP

volts? millivolts? microvolts?

Makes you wonder what put the divot in the lower side of the blade...

Of course it can, it is spec'd at 600 ohm load. And all op amps are short circuit protected...

Which is why I posted...

That circuit that you pointed to the smoking resistor is the headphone amplifier...

Did you look at the output signal with your oscilloscope to observe the waveform at the output of Q701?

Why was the original replaced?

Uh oh, sequencer envy...there goes more money.

R721 is in the zoebel network for Q701, the headphone amp. I would suspect that for this to be getting hot, that Q701 has a high frequency oscillation going on when you crank up the treble.

Yes, provide a schematic, the board artwork will take too long to reverse engineer.

Told you Kyle...enjoy the project

Minimize scuffing off of the solder mask around by the washer and nut. Once you scuff the green solder mask off, bare copper gets exposed right underneath. The only tinned areas of the board are those that do not have solder mask on them, around holes and such. You will note the screw head is...
