Dead reverb.

Found disconnected wire on reverb tank rca connector. Simple fix.

Thought I'd share pics of this beast as it's not common.

That's quite the giant power transformer for a 40-watt Fender amp, looks substantially bigger than even a Twin.

what year is that amp? 1993? eleventeen I think these are 60w amps.

The schematic says 1993.

The first thing I noticed were the huge PT.

The PT looks like a Hammond 290SX which they list as a replacement for Fender Vibro King. http://www.hammondmfg.com/pdf/EDB290SX.pdf

It also looks like they closely studied CBS Silverface wiring methods..
