This tank 9BB2C1B is not compatible with 9BC2C1B and we do not have a replacement.

The input and output impedance are the same. The difference between this tank and the 9BB3A1B is the tank connectors. Your tank has grounded input and output connectors and this tank has an insulated input and a grounded output. These are in place to prevent ground loops and unwanted noise from occurring. Unfortunately we are unsure how this will affect your amp and its ground loop scheme.

Unfortunately we do not have that tank. You may want to contact Mesa Boogie for a replacement.

It should. The dimensions are 16.25 in. x 4.735 in. x 1.313 in. so you will want to make sure using those.

Installed this in my Rivera 55-12. The old unit had broken a spring. Fit in no problem, and sounds great.
