Hi my friends!
I will have next week one RCF AS 6001 amplifier to repair, I please asking to anyone for shematics/service manual for this amplifier.
To me looks like one Class H 2 step  configuration amplifier, at "first seen".
 
Someone tried to "fix it" using fake output MJ devices and fails in first minutes... Angry
 
Thanks in advance, regards, Claudiu!

Looks like it's actually Yorkville AP3000 series.

Thank you very, very much!  Thumbs Up
 
Seeing schematics, it looks most like a classG amplifier.

No problem. Smile

Edit: When you have time, open one of those weird marked MJ15022/23. Let's see the sucker inside.

I have never seen such logo. Perhaps made in India ? @Kevin, since when do you have them ? Looks like an old batch. Question

A few years. A customer sent an amp in for repair and told me "don't get any transistors for it, I will send some' and he sent those (in CPC packets). Which is why I fitted ON Semi transistors and kept a couple of those as a souvenir.

@Kevin,
