The Mod Electronics 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.

Currently have an 8AB2A1B, will the difference in insulated/grounded ins/outs still work?

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

Will this work in a Hughes and Kettner edition 20th anniversary as a direct replacement? The original tank is STAMER 008-CB3E1E-STA 959006.

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.

Will this work in a Fender 68 DRRI?

The stock tank used in that amp is a 4AB3C1B, and this tank is the same in every specification other than the third spring and the slightly differing input and output impedances. This should be compatible with the amp in question, but will not be the exact replacement.

Is it useful if I use an 8ohm input reverb driver transformer instead of 10 ohm?

This reverb tank will work the same as a 4AB3C1B and should be compatible with any transformer used with a 4AB3C1B tank.
