Silvertone 1472 Guitar Amp - Tremolo repair

[ohgoodthinking99]

Hi all, this is my first post. (Copied into a new thread at 52 Bill's suggestion)

I have trouble with my 1472 tremolo (it basically doesn't do anything).
I've done a little ground work. As best I can tell, all my resistors read about what they should.
My 1MEG speed pot with the power off reads 0kohms when fully up, and 980kohms when fully off.
When powered up however, it still reads 0kohms when fully up, but when decreasing the setting, I get to about 6 on the dial when it peaks out my meter beyond 2Mohms.
Is this normal or is my pot shot? Other than I'm down to caps, and I don't really know how to test those.
Thanks much

Welcome to the board. I'd suggest staring a new thread as this one is already 2 pages deep.

As for your question, you can't read the resistance of the pot while the amp is on, because there is a voltage appiled to the pot from the circuit that will throw off your readings. In fact reading resistances while the amp is on can be very dangerous.

The things for you to check are the tubes and the caps. If you've already checked the tubes and resistors in the trem circuit, just order replacement caps for the trem circuit and replace them. 99% of the time, this will cure your problem.

Bill, thanks much for the welcome and the quick reply.

I've tried several known-good 6AU6 tubes, so if resistors are OK, it looks like my best move is to replace all my cap's. Thanks, I'll see how it goes! We have http://www.tubedepot.com/ here locally, so I'll see what they have.

Thanks again,
Dean
