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.

Typically the Vox AC30's take a 9EB2C1B.

Yes, it will. It has a longer decay than the 9EB2C1B.

If you are referring to the mounting plane then we would not have a 9AB3C1C.

The mounting plane for this tank would be horizontal open side down.

The Input and Output impedance must match in order to be an acceptable replacement.

We wouldn't advise using a tank that has different insulation points and input and output impedances. We do carry a 8AB2A1B in both the MOD and Accutronics brand that you can view here: MOD Tank https://www.amplifiedparts.com/products/reverb-tank-mod-8ab2a1b Accutronics Tank: https://www.amplifiedparts.com/products/reverb-tank-accutronics-8ab2a1b

This appears to be a different tank than the one in question. The most important specs that are required are the input and output impedance. If your amp has a 10 Ohm input and a 2,575 ohm output impedance, this should work for your amp.

There is a schematic online that shows a Hammond IV C. If this is the same as a Gibbs type C, the Accutronics code is 4FB3D1B. Please check the schematic along with your amplifier to confirm.

I've had a Limited edition (12 inch alnico speaker) '65 Princeton Reverb re-issue for about a year, and, though I really love the tone of the amp, I never wanted to add any more than a tiny bit of reverb because the factory unit had an irritating flutter. I replaced the original 2-spring short decay tank with this 3-spring long decay unit and the improvement was dramatic - a smoother, fuller sound. The swap was easy, but I did notice that the color code on the input and output connectors was different from the original, so make sure you connect your new tank using the in and out labels as your guide. Thank you, Amplified Parts, for having such an informative web site.
