Hi All,
I noticed a previous thread on an Audiosource Amp 300 that was sparking so I thought I would post about mine, it's been used for many years as a multi zone amp for 5 different zones going through a Russound Pro-6. What I'm seeing now is that the amp will run for a while but the audio is a bit distorted and lacks bass in the zone speakers but will eventually shut off on 1 channel when getting heated up and then the other. The Amp light is still Blue, and when I shut off the amp, then turn it on it will begin running again for a shorter and shorter periods before going into protection again but not showing a red light, still just the blue light. I took off the top and did a visual inspection, and dont see any burnt mosfets/resistors/caps in the power board, and don't see anything visibly wrong on the signal side either. Can anyone give me a starting point for trouble shooting and a direction to head to solve this, as I don't think it will be worth sending it to a repair shop, that bill would be more than buying the amp used on Ebay LOL help! While it does look a little dark around IC01 and IC02 (and I have seen on some other forums this seems to be a common problem) the board isn't burnt or anything. Anyone having some simple trouble shooting tips would be greatly appreciated as it seems like if that's the issue that's a pretty simple swap out.
Looks like IC01 says AUK 526 s7815 PI and IC02 says AUK 444 7915 PI is there a simple trouble shoot? or should I make a play to replace both the ICs and maybe the resistors in front of them for safety? R02 and R03 ..... The Caps don't look bulged at the top to me.
