Set the controls for the heart of the pun
you mean in the circuit? while it is on and idle?Put your multimeter in Ω's and measure its resistance.

Never. I mean never measure Ω's in a live circuit. Yes measure there resistance in circuit with no power applied.you mean in the circuit? while it is on and idle?
Looks good to me..FR101 looks burned as you can see in the picture but measures 68.2 ohm
He is not just good, Avionic is the best!dude you're so good at this. bingo with the small detail that it is Fr101 that looks burned. Fr102 is for channel L i think. it is a white unusual looking resistor.
It is time to make some voltage checks on various components. Without the outputs in circuit.Remove the two right channel output transistors. Make a note of which one goes where.
Just unscrew the transistors and remove them from there sockets.Try not to damage the mica insulators.
before i do that let me tell you something. i apologize if this will throw you off or just plain annoy you because it probably is due to my amateurishness but i went back to measuring the idle voltage for the electrolytic board which is the last item on the table here:It is time to make some voltage checks on various components.

What is your geographic location ?before i do that let me tell you something. i apologize if this will throw you off or just plain annoy you because it probably is due to my amateurishness but i went back to measuring the idle voltage for the electrolytic board which is the last item on the table here:
the one that they call indring current by the typo that you pointed out earlier.
now it is unchanging zero for TP2-TP4 which is channel R
and it is also zero across TP1/TP3 which is channel L but it does change. every few seconds it jumps to 20 mV to 30 mV and then it jumps back to Zero.
if you want i can take a video of this behavior.
the only difference from 2 days ago is that i saw some white smoke come out of something right after i meade the measurements that i told you last time and i failed to figure out where it came from. it was a little (due to a small componenet)
when i saw the brown color on FR101 i saw aha that was it but i guess not. it came from something that was close to the heatsinks. possibly on the lectrolytic board.
So you haven't figured out what component smoked yet.i saw some white smoke come out
nopeSo you haven't figured out what component smoked yet.
