The replacement reverb tank should have both input and output jacks grounded. If the input jack is not grounded, there will be no complete circuit and the tank will not be driven with any signal.

All plexi front amps use this same type of tank. In the latter metalfront amps, the drive circuit places the input coil of the tank in the feedback loop of the driver chip, so these tanks need the input jack isolated.

All standard Accutronics tanks (and most other manufacturers) use the same codes on the tanks. The fifth place character describes the input and output grounding schemes. A= Input and output grounded, C= Input isolated and output grounded.

If the tank you bought has a letter C in the 5th spot, then you will need to jumper the ground at the input jack to the chassis ground of the case.
