Requesting PM1200 Schematics

Post by fallenfacefirst » Fri Nov 23, 2012 2:22 pm

I'm looking for a schematic for a Carver PM1200 Power Amp, it's old but we do a lot of repairs and can not find schematics anywhere else so I turned here. Any help would be appreciated thanks!

I have this specific schematic unfortunately it's for a different model, and very hard to make out some of the resistors and their values. It doesn't line up with the specific amp I'm looking for, an older 1200 power amp model maybe from the late 80s? Not to sure of the time frame.

Looking for the values for
R58
R25
R60

And the value for the resistor across the bridge rectifier.

Thanks for the post though.

If you look at the schematic posted on ebay you can see the values of the resistors in question.
r25=470 ohm 2 watt
r58=6.8k 2 watt
r60=3.6k 2 watt
I see a resistor across D1 which has the markings for a bridge it value is 6.2k 5 watt
maybe this is what you need.
