Gotcha! New ones will be in order then... Thanks for the clarification on those . .

The shedding is the layer of grime that I carefully scraped away in a few places to show how dirty it was. The wipers don't look work much at all. This is an analog unit, nothing fancy, I have to believe with good wipers and cleaning the resistive element it should work. After cleaning them and...

Ok, am I missing something here? Is there supposed to be another piece\part other than what is pictured here? ... That's the tube gain pot ... Same layer of crap on the element. What makes it damaged?

Dug in again .... Bigger magnifying glass, brighter lights, sound multiple solder joints on both preamp tube sockets. So I went ahead and be solitary connection on the board. Move to the front board. No noticeable loose solder joints so far. But I did find this ... .... That's the master volume...

connected like the above, ive got all the volume i need!! connected this way pretty much exactly the same symptom. so ... problem is most likely in the preamp then ?? FWIW when connected like the first quote, and the v4bh in standby, cranking up the main volume and gain all the way produced...

Oh, and here's the pencil I used. My pop told me this was safe. I figured he would know. 35 year electronics engineer for General Dynamics. Or maybe he was just messin' around, hoping I'd get lit up

That's what I figured. Guess I was hoping that someone else had experienced this and had the cure all. Seems like such a simple contraption as things go these days. Now to find a tech that can read between the lines and find the culprit. Thanks again .... I'll report back when she's back in...

ya, didn't mess with the solder. connected all the wires, fastened all the board screws. rechecked the bias(i'm aware its not related to my problem) which came up from 21mv to 26mv, from just the cleaning i assume. Plugged it in. Same same. No change. FYI-I did not tap inside the live amp with...

OK, so I cleaned out all tube sockets, wire connectors, input jacks.....NO CHANGE! Things I did notice after restarting the amp. with all volumes down all the way, tapping on the board with all the rear input jacks produces very large speaker crackle. Just finger tapping the jack holes without...

Ok. Patch cord jumped across send and return, no change. Touching end of patch cord plugged into send = no effect, touching patch cord plugged into return = normal buzz. Patch cord plugged into footswitch = no change in sound, peak\mute light illuminates. Shorting patch cord = no change...

Thanx for the responses. I will check the effects loop in the am. Too much Turkey day food! cant see straight!! What's the best procedure for cleaning the effects loop? Most of the time I've had this amp I've had an Alesis 3630 compressor,and Korg DTR-2 tuner connected to it. Including the 10...

Hello to all and thanx for any insight, instruction, and assistance in advance! I'll try and keep this short but add what info is prevalent... 199something svt-3pro, used it for rehearsal and gigs maybe 4 times a week for a good 3 years. then it went on a shelf, for at least 10 years...
