So I finally had some free time and got to checking those pins with my meter. Here's what I got:
Diode test setting
Red probe pin 11 / Black probe pin 10 = 1.5
Red 11 / Black 9 = 2.1
[I][B]Red 11 / Black 13 = 0.017[/B][/I]
Red 11 / Black 14 = 2.1
Then
Black 11 / Red 10 = 0.55
Black 11 / Red 9 = 1.00
[I][B]Black 11 / Red 13 = 0.017[/B][/I]
Black 11 / Red 14 = 1.01
So it looks like [I][B]11/13[/B][/I] is shorted, correct??
[I](When I changed it to the Ohms setting 11/13 was the only pair that beeped.)[/I]...

This the area you are referring to? I went in with a toothpick and small brush and cleaned off what I think you were talking about, it did look like the legs of R412 and R416 had some corrosion on them. Might try and unscrew the board and check out how the underside is looking....Leave a comment:

HH Scott Model A510 Stereo Integrated Amplifier/ Graphic EQ - Blowing fuses in the LEFT speaker channel only. Any Help???
So like the title says, I have an old Stereo Receiver/Amplifier that I picked up from the goodwill, it's a HH Scott Model A510. When I first got it home it had zero output. Opened it up, notice the fuses are missing. Pop in 2 new fuses (AGC4A 250V) and try again, within 5 seconds the L channel fuse POP! I don't see any visible indications of damage or arc burns on the PCB, no popped resistors or diodes, no burnt traces or blown out caps. So I decide to just try another new fuse, POP. Swapped around my R and L speaker wires, and checked the integrity of all wires and connections. Everything looks... -
Hello world!
I came here looking for assistance troubleshooting an audio receiver that's refusing to cooperate and do it's damn job! Although chances are I'll probably stick around even after this project, because the truth is it won't be long before I'm elbow deep in the next project and it will be nice having someplace where I know I can seek help, instead of just panicking and eventually abandoning the project. 😂😂😂 Oh yeah, I also have really bad ADHD. Sometimes it means I ramble waaayyyy more than I should, or even intend to. So this is me apologizing ahead of time for...Leave a comment:
