Have Pioneer ever made a real Class A amplifier?
They often call their Class AB amplifier for that.
How old is that Pioneer M22 ?

Pioneer M22 Power Amp Schemetic
 
Hello Halojoy Thanks for giving the information.
I recall Pioneer manufactured the M22 power amp in the mid - late seventies. I am not sure is it a real Class A power amp but the heatsinks are quite hot when amp is working.
I have the M22 power amp and the C21 pre amp but both amps needed to re-store so I need the schemetic to do so.

I think I read 1977-79 in the site.
I think it is real Class A Amplifier.
And probably some of the best Amps Pioneer ever have done.

You can be proud to be owner of such a classic amp.
Vintage collectors like that model,
and would give you a lot of money for it.

I believe most of the modern amps' sound quality are better than these two amps but I like these two amps especially the body styling of the M22 and I considered these amps were the two best amps that Pioneer have ever made that is why I want to re-store them.

Pioneer M22
 
is this theme still actual?
I own a Pioneer M 22 on my own. I have repaired it on my own. Since I am physicist I know what to do. If you want me to repair it, I will do it for 500Euros. If no interest let me know if I can buy the M 22 from you for 400Euros. Best regards.
