    found replacement

    When I did a rebuild on my '67 Deluxe Reverb, I found a reverb pan that didn't really look like a Fender style reverb pan but worked nonetheless. It measured out ok. I tried it in the GA77 and it worked fine. Then I remembered that I got that pan from a Kalamazoo Stereo 30.
    I guess the pans are close enough to interchange.

      Looking at the schematic, it's a typically transformer-coupled reverb circuit, and the Accutronics 4AB3C1B used in many Fender amps should probably work fine.

        Actually, I thought some of these used a capacitor coupled circuit, more like the Ampeg circuit without the transformer.

        What is the resistance reading of the input transducer of the tank that you ended up using?
