AB 600 Schematic needed

Original Burnedfingers · 2nd April 2006, 08:26 PM

Anyone have an AB 600 amplifier schematic that I could have a copy of?

This would be the AB International amplifier. The original 600 with the 1B04 outputs. The Precedent Series.

Hi Joe!

Hmmm, I have the newer one that looks like a Leach.

I think the original is close to a textbook RCA design. I have the old RCA SSD204 handbook that has the quasi-comp designs for the 1B04 (if that helps).

Hi Dennis,

Thanks for the reply. This one unfortunately is not like the leach.
Someone tried to change some caps and got the wrong values and soldered them in the wrong spots. The price was right as its a zero dollar investment so far. I'll call AB and have them send me the parts list and schematic.
