Any one know how to fatten up and slow down the Tremolo?
in one of these amps?
I've gone through it once and have the whole amp working
fairly well. Not great mind you, but working.
The Reverb is passable, not like a Fender at all.
AND
The trem is very fast and whimpy, even Maxed out,
with speed 0 and intensity 10 there is no trem.
With speed somewhere in the middle it is so fast
it is like you'd never use it.

There are two sets of caps that I've replaced,
they are the .02uf and and .1ufs in parallel with
.01uf and.01 uf separated by 1 meg resistors to ground.
Tweaking trem circuits is not my forte, but I was thinking
of changing one or both of the .01s to .1uf and see if
that worked.
In the schematic, the trem is just to the left and in the
lower center.
The 1 meg is the speed pot and the 500K is the intensity pot. It is not so intense either.
I'm not so sure the amp is worth the time and effort.
This is a fairly rare amp as they were made only for
1.5 years and subject to major failure due to heat.
Thoughts anyone?
PS - If anyone has one and would like a US voltage
power tranny, Mercury Magnetics blue printed them
and this amp has one installed.
