Turbo duo sound issue. Capacitors changed op amps are fine.

[Nunhunter]

If anyone can help out I would appreciate it. At q603 and q604 atm. What's the voltage suppose to be at. It's bouncing 5-11v. Guessing corrosion short or open trace maybe damaged via.

[Keith Courage]

It's normal for q603 to fluctuate a Little. Starts around 0.11v here then drops to about 0.06 steady.

Q604 seems be steady around 0.20

Funny enough, I passed this along to thesteve, but Nunhunter already knew him on Facebook and he was already trying to help, heh.

[Nunhunter]

Yeah Q604 and Q603 are both fluctuating at around the same voltage. between .10v -.16v i measure the bottom left and bottom right legs. nothing constant. is that normal?

The Steve helped me out. turned out to be corrosion on c322 to amp 503 and ground.

Cool, he's still got it!

It's good to have these cases documented somewhere for others to search for in the future.

I'm torn between DIY or just sending it to a pro and not wasting my time biting off more than I can chew; you have to recognize your limitations and not go too far. I still have a full capacitor replacement job to perform on my Turbo Duo, and I'm worried if something like these kinds of issues happens before that.
