First a unike looking amp.Low hour unit, in original condition, from around 1975.Pioneer M22
I remember seeing those years ago, but I have never heard one... How do you like it?
When in original condition its a very nice sounding amp.. lots of 3D.. Its not super transparent, and dont have a lot of power, and it runs very very hot.. I bought quite a few defective ones,and had pretty much luck reparing all of them, replacing all the transistors with original NOS ones, and replacing the caps, and some resistors.. Think i have 5 or 6 of them still.
the best part of all my amps..I always scoured to find good deals...knowing I could try them out...then flip them for a profit...which worked on all except one which I lost 50$
