Title: looking for a peavey triple xxx schematic
Post by: phsyconoodler on April 05, 2012, 06:03:09 pm

I need a schematic for a peavey triplexxx  100 watt head but I can't seem to find one anywhere on the net.Anyone know a link to one?

Cheers!

I just email Peavey customer service for schematics... they are very friendly and accommodating.

I found a schematic but now I have a burnt resistor, R64SUB it's labelled but nowhere in the schematic or in the BOM is the value of that resistor shown.Nowhere.

  I looked and looked and looked,but it's just not there.It's a large green,wirewound and the burnt part has taken the value with it.
Anyone see what I'm not seeing?

It's gotta be in the power supply. If ther are no others like it then it's not a screen resistor. Maybe it's the one between the first and second filter caps?

Thanks guys,I actually called the peavey tech support line and he sorted if out for me.Seems like either a fuse or this resistor blows when a power tube shorts out.

  400 ohm 10 watt flameproof.Very hard to nail down by looking at the schematic.

Very helpful guy at Peavey! My hat's off to him!
