Carver PM-600 schematic please

[rusking]

I have this dying Carver PM-600 amplifier.
Tr 222,tr 103, and tr 102 have all gone s/c.
What I would like to do is to replace one of the internal supplies
with a current limited external supply while checking it through.
Without a schematic I am lost.
Can anyone help.
Thanks.

Why does an amplifier need twenty power transistors?
It's electronics gone mad !

so have TRIED to antispam my address.

These amps are critical to work on. There are many output transistors to
give a good steady solid output to any type of reactive load, such as a
descent speaker. This is a very high end unit. Many of these high end
amplifiers have a lot of output transistors. When replacing them, they must
be in matched sets to have proper reliable service.

As for parts and service manuals, you will have to contact Carver directly.
I have not dealt with them before, but I suspect that they will not sell
service manuals or parts to outsider servicers. Many of these very high end
manufactures are like this. You most likely will have to send them the amp
for service.

Thanks Jerry for that.
It certainly looks impressive.
It comes from a school here in the uk
and the teacher who sent it in for repair
inherited it from another
who purchased it and has since left.
Someone in our workshop looked on the internet
and told me Carver closed down or were taken over in 1999.
Even if Carver was still there
I think the cost of shipping and the repair
would be more than the school would want to pay.
They would probably rather replace it with a less exotic one.
Pity to scrap it though!
