The GA15RVT schematics I can find don't have a reverb transformer. Can you post a schematic of your amp? Better yet, post a pic of the actual reverb transformer.

A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

keep file size below 1024k
email it to yourself 1st - usually gets resized, use a image viewer that allows for resizing

I believe you. Gibson is well known for lack of technical documentation. I can find pics of your amp but I cannot find a proper schematic. Without a correct schematic it's just a WAG if the fender transformer will work. Can you draw a simple schematic that shows the driver tube and it's connection to the transformer?

Where did you find that?

I have a folder on my computer where I collect schematics that I haven't seen before.  Somebody somewhere around the forums posted that, but I've long since forgotten who.

Looks like a Fender reverb transformer will work as long as it's driving an 8 Ohm tank.
