I have an Hitachi HA-330 stereo amplifier I purchased new in 1976 and it has worked flawlessly all over the world until a few months ago - the left channel is getting flaky and the left output wattmeter has quit. I lost the circuit diagram in one of my many moves, and am looking for a scanned or faxed copy to work with. I love this old workhorse and the audio specs beat most modern stuff.

Anyone able to give me any help with this?

Thanks in advance!

No luck yet - thanks for your interest, hope you have better luck than I have had and maybe, between the two of us, we will be successful. I emailed Hitachi also, but no reply from them either. If I get a circuit diagram, I will be sure to let you know.
