Hi folks,
I've been a member of this fine site for a little over a year, lurking and soaking up the knowledge...
I stumbled into a 5000x with a dead channel for $15 last week and decided to take it on as a "practice project" before tackling the restoration of my dad's Pioneer SX-750.
I have been reading up on old threads for the past couple of days, and haven't come across an answer to my particular issue. The unit output is fine through the pre-outs feeding a good amp, but I get loud static that doesn't change with the volume control through the right side when the pre to main jumpers are in place.
My dilemma is this: At some point the left driver board was smoked and the repair looks to have replaced all transistors on the board as well as the outputs. The resistor values (see attached image) were changed, I assume to drive the new transistors properly. The repaired channel sounds good.
The question is do I "follow the leader" and repair the dead side to match, or use the correct cross referenced transistors for replacements and don't touch the other components. I guess a third option would be to replace components on both sides to factory spec.
Opinions???
