I'm probaly looking at the same schematic you are, but I can't be sure.

perhaps you can post your schematic and call out a few readings you've taken

if Its the same schematic what are your high voltage readings at B,C,D,E and F .

then check voltages at pins 3 and 6 on V1, V2 and V3 each to ground

I probaly can't trouble shoot your amp, but I can suggest a way (see above) for you to convey your delema so that one of the guru's here can be of assitance without them having to dig the information out themselves.

the guys here are great and do this stuff for guys like you and I at no cost. It's up to us to make fixing an amp long distance feasable and worthwhile to them.

have you tried some of the basic troubleshooting things like wiggling wires(use chop sticks when plugged in), checking pot are working correctly, capacitors are ok, tubes good, tube sockets clean, cold solder joints, OT is not open on either side, input and speaker jack have good contact and the list goes on



I sincerley apologise if I sound like a jerk, thats not my intention at all

your post seems vauge and I and I'm sure many other members want to help you get your amp back in top shape.
