solder

I will try the two irons as soon as I figure out how to vacuum the flow.
I do not have a vacuum pump. Only two hands also.

Attached is a picture of the cap area.

solder

How did you keep from burning the cables did you desolder the surounding cables or did you have a heat resistant material to protect the cables?
Also,
once the metal starts to flow how did you wick it?

Bassman

I think I will leave it alone and see what happens. You are right worst case I lose the power tube.
Hopefully not while playing.

Going to go play the 1950 Valco.

Re: 1974 Bassman 410

Yes, this is Gerald Webers book. This is a 50 watt two power tube amp. I was thinking the dropping voltage resistor might be the issue. I am not sure what value to put in its place. It is a 3.8k resister now. Would you go to a 5.6k? I do know the power tubes were a matched set. At least according to...

1974 Bassman 410

Did mod 2 on diagram no volume. Reverted back to figure one keep the 220 ohm resister instead of the 100 ohm resisters, but have 10 volt difference between neg voltage on the output tubes.
Is this a problem?
Amp sounds great though.
