Installed in a mid 1970's Fender Deluxe Reverb. Works well, easy replacement.

Got this to restore a ‘69 Plush P1000S which pretty much a direct rip off of an AB763 Twin Reverb. Took about 10 minutes and the reverb was back to life- rich, drippy and full. Great product at the cheapest price I could find. Thanks AES!!

I'm not seeing anything matching those specs but if Hammond Manufacturing produces one we could special order it.

Hello, we do not know if this will work in your amp. You could contact Fender or try to find a schematic for your amp.

This is the reverb driver for some Twin Reverbs. It has a primary impedance of 25,000 Ω with an 8 Ω secondary impedance. This is the most common Fender reverb driver. I would confirm these specs with your schematic.

This is a replacement reverb driver for the Deluxe Reverb, Pro Reverb, Super Reverb, and Twin Reverb. With that in mind, these amps used a 4AB3C1B reverb tank.

We do not have sufficient cross reference materials to verify what tank was used in that amp. We suggest you inspect the original tank (provided there is an original tank) and see if there is a model number anywhere on it. If there is no tank, we advise you consult a professional amp repair tech.
