Hello all,

Could someone please provide me with the correct accutronics number for the reverb pan in a Super Twin Reverb ? I believe I have the wrong pan and cannot find a reference listing the correct one.


thank you.

Really......?

I've got six reverb-equipped Fender combo amps from that time period and not one of the reverb tanks says "Accutronics" on it. None. They're all built by Gibbs (under license from Hammond).

The best course of action might be to find someone who owns an original and unmolested Super Twin Reverb and ask if you might inspect the reverb tank to ascertain the salient details. The critical parameters are the grounding scheme at the input and output jacks and the input and output impedances. Once those have been determined the data may be used to cross-reference what's available from Accutronics. Much of their stock is now made offshore but try to find an older US-built tank.
