A friend recently bought quite cheaply an old 8000A amp. He only wanted to
use the power amp sections, but one channel is now misbehaving. Hence he
has asked me if I can investigate and fix it. Since I am unfamiliar with
the circuit details, and know the design is held in high regard I am using
the chance to learn something about it. :-)

Alas, he has no documentation.

Does anyone have a copy of the circuit diagram, layout diagram, service
data, or even user manual for the early 8000A amplifier? If so, I'd
appreciate a copy of any info of this kind. :-)

Slainte,

Jim
