Hello,
I am starting to dig in to my hoard of old amps with issues and am looking for a schematic/service manual for a Nakamichi PA300II (and PA350 as well). This one I have apart was previously repaired with a bunch of ECG transistors so I would like to get it back as close to original as I can. Thanks for any help or info.

I believe the link above (comes back 404 error.) is for the first generation which is different. The site has a link for the second gen but joining is blocked for now.

Those are great amps! I have one of each and was authorized warranty.
Yeah, get rid of the ECG parts. That repair was done by an idiot.

Oh, he's also limiting downloads more than before.... I guess too many people are creating too many fake accounts and abusing the service.
Oh well, sorry about that.

The II version isn’t on hifiengine, only the original version.
I thought the only difference was in the power supply(?)

Don't know what the differences may be. Way back when I was working in the 12v industry, ECG parts were considered a last resort. The whole power supply has been replaced. on this particular amp. I have more so it is time to unclutter my work area and open em up.
I'd have to dig out the manuals to see the difference. It was a few years ago. We simply used the correct manual for the product, not concerned about differences.
ECG parts were absolute junk, liabilities. If I see anything with an ECG part in it, and it has a real replacement for the original, the ECG replacement is in the estimate, mandatory.
