One source with a couple dozen different units available is amprepairparts.com.  They carry replacements for most Accutronics units.

Here is also a link to a page explaining the Accutronics numbering system that is based on the various aspects of the reverb unit...i.e., input and output impedance, decay time, mounting method & connector locations.

Another good source is Antique Electronics Supply. They also list their tanks by the Accutronics numbers mentioned above.

My info says the tank should be OC Electronics Z3C.

O.C. Electronics was acquired by Accutronics in the mid 80s.  Perhaps they can provide a cross reference to their numbering system for the Z3C unit that Loudthud pointed out.
