Fender Quad Reverb project

[Jerry Shaw]

I just picked up a Quad Reverb in pretty rough condition, but it
(mostly) works.

I think it's a '78 or '79 push-pull master volume, because when I
pulled on the mv, the shaft pulled out of the pot!

It's missing the reverb tank, back panels, and two of the original
speakers, which were replaced with some no-name 8-ohm speakers (which
were not connected). For now, I'm running it with the two 16-ohms and
one 8-ohm to get a 4-ohm load.

How do I determine which is the correct replacement reverb tank? And
does anyone know the dimensions for the back panels?

It's beat up and ugly, but the chassis appears to be untouched, and I
got it for next to nothing, so ...

Thanks,
JS

You can buy reverb tanks from Accutronics directly
on eBay... they custom build them for you from your
own specs (or they can provide). You have a standard
Fender-spec reverb tank, btw, nothing special. However,
this is your chance to order one with vetical mounting,
if that is the way Quads are slung (SuperSix's are).
The orientation of the tank makes a difference, and Fender
never cared to mess with it, but you can if you choose.

Same price as everywhere else, too.

I recently got one cheaper at Ampwares.

Thanks Stephen and Dave...I'll look into both places. BTW, the Fender-
Utah speakers and the pots were all manufactured 49th week of '74, so
I guess that would make it a 1975 non push-pull 100 watt amp.

The reverb tank commonly used in twin reverbs is an
Accutronic type 4AB3C1B. It is meant to be installed
at the bottom of the cabinet (open side down).

If you want to mount it on the side wall of the cabinet,
you need either a 4AB3C1E or 4AB3C1F depending which
end is facing up.

Here's a link for your reference.
