Danelectro Viscount how to increase tremolo speed?

Postby retrobob on Sun Nov 08, 2015 12:24 pm

I have a Danelectro Viscount model 143. The tremolo when maxed out, with speed control on 10 produces a slow trem effect as if it were on 0.
When turning the control counter clockwise, it goes even slower until no effect is heard when halfway down.
Any idea what to look for to get a normal tremolo working? :think_1:

Thanks.

You'll need to pull chassis and find the out of spec component, usually a cap in the trem oscillator. Don't dig around inside without discharging filter caps, or if you don't know what you're doing. Actually a pretty easy fix.

Also, might just be a bad tube, a 6AU6. Pardon my memory on a possible bad tube!

Thanks Rocco, for the reply,
I actually found two .02 caps close to the 6au6 that had drifted up quite a bit.
Replaced those and whala!

Now I need to try and get the trem strength a bit stronger. The tube seems to be good.

Check all the components in the trem circuit, my guess is it's the .05(.5 ?) cap.
