Compatible with Ampeg® amps that require the original spec, type "C" reverb tank with insulated RCA jacks.

The MOD® Reverb Tanks are high quality upgrade units. Some of the major differences between the MOD®s and other reverb tanks are that the Transducers are wired directly to their respective RCA jacks as opposed to current production tanks where Transducers are connected by a detachable plug to their respective RCA jacks. This makes the tanks less receptive to any outside interference. The original Hammond Accutronics tanks from the 1960s were also wired directly to their respective RCA jacks. In addition, very close attention has been paid to the spacing and size of the lamination of the Transducers resulting in a more vintage like tone.

We simply do not have the resources or reference materials to determine if this will work with your amp. If you have the original tank, I would look to see if you can find an eight character code such as 4FB3D1B on it. If not, you may need to do some research to find the correct tank number.

Unfortunately we do not have any cross referencing materials on this amp and do not know what the proper replacement is.

You are correct that the mounting plane is going to be different, but also the connectors for this tank are specified as being Input insulated/output insulated while the connectors on the 4FB3A1A are going to be grounded Input and grounded output. The 4FB3A1B would be the right tank to do what you are trying to achieve.
