There's lots more than just the 65 volts. Probably + and - 65, 45, 13, etc.

I did check the supply and it is a good clean 65Volts. All the connections
also look great. Especially for a 25 year old amp. I will look some more
today...thanks...Ross

I don't know - Pioneers are NOTORIOUS for regulated power supply
problems.
The timing of his failure also suggests this to me.

Hi Folks,

I have a Pioneer SX 1250 Reciever that is giving me problems. It
shuts
down
after about 30 minutes and the right heatsink seems warmer than the
left.
I
have the service manual and have run a few tests but thought I might
ask
around before I spend the next couple of days fighting this
one......thanks
for any help....Ross


If it plays normally otherwise, I'd bet it's a bias problem. The
carbon
trimmers they use to set bias are pure garbage, and they'll drift just
looking
at them. There might be two adjustments per channel on this model.
Flush
them
out with a quality cleaner, and see if they set up normally. If so,
replace
the pure garbage pots with mere crappy ones (one grade up and re
adjust
the
bias.
