I posted a few days ago on reddit about an Accuphase P-300 that I'm having some minor problems with and someone suggested I come here for more help.
A few years ago I came across an Accuphase P-300 amp for free on craigslist and immediately snagged it. Got it home and it wouldn't turn on, but a little PB Blaster on the power switch solved that. The thing sounds really amazing, but the left and right channels have never been balanced properly - I've tried at least 10 different sources and 3 different pairs of speakers, and in every case the left and right volumes have to be set wildly differently for the amp to produce the same output volume in each channel. I can't remember which is higher at the moment, but that's easy to check.
I'm not particularly comfortable dismantling and repairing it myself, but I'm willing to learn. I have some experience with EE - I can solder alright and I know what most things are called and look like IRL and in schematics - but mostly small things like RasPi boards and and gaming controllers.
I was able to find the schematics on HiFiEngine.
Help me Audiokarma, you're my only hope!
