Peavey Triumph PAG 60 repair questions

[TomCarlos]

Gibson.... Go look at stock photos of the PAG. I do not believe a fan was standard equipment. My guess is that someone added the fan.

As for the popping .... If your amp is anything like the Triumph I worked on, check ALL of the ground connections. This includes screws that connect the chassis to the PC board. In my case, I spent hours looking for a persistent pop. I soldered just about everyone point, checked the molex connectors, check all the cables, etc. Be patient, move from left to right and use a magnifying glass to check from cracked solder joints. As for the reverb, leave it disconnected for now, until you resolve the other problems. By the way, what is the ID # on your reverb tank? Check to make sure it had the correct tank to begin with.

Thanks for the response. The tank is an Accutronics 71011114. When I turn of the reverb through the footswitch the amp behaves much better. I did take my time looking over the main board for cold joints. I reflowed about 100 joints. The majority of those were all of the potentiometers, I also hit the reverb and all the molex connectors. I also cleaned all of the connectors that goto each board. Those molex connectors are a real pain in the ass. I use a visor with three different magnification options and a decent bench light. I'll take it a back apart and take some more time going through the amp. I'll need to do so to remove the main board to replace the clean gain pot.

Just a quick photo so show what I did, practically on all PC boards. I scraped the traces to make sure I have proper solder flow from a pin to the trace. I did this on tube sockets (and I replaced three tube sockets) and the pins for the molex connectors. In this photo, you can see my work in progress. For the tube sockets, I wanted to make sure I had adequate connectivity on both sides of the socket pins.

It's a slow and arduous process - take your time.

The tank is an Accutronics 71011114.

That is the correct part number for this amp. The generic part number would be 4EB2C1B.
