Reverb plus loop?

[ER]

I was going through my junk and found my old danelectro reverb unit that quit working years ago, well it has a 12ax7 1.5mA, 6c4 1.5mA, and 6x4 6mA rectifier so I should be able to run enough tubes for a loop and the 3 tube reverb with a SS rectifier and have room for my 3 spring hammond tank all in the original case.

Need to check the secondary voltage still. Didn't want to mess with it too much because of what looks like an asbestos board in the spring compartment. It's got a funky single spring driven by a piezo, I figure that's where it died.

Any good designs out there or just do a dumblator and tie in the #13 3-tube reverb somewhere?
