5.00 out of 5 based on 2 reviews
Taylor McIntosh - March 26th, 2024
5 out of 5

I ended up having a bad rectifier tube and two possibly bad 6V6s in a 1972 Fender Deluxe Reverb I was rehabbing.
Along with a new bias cap, from AP, and two new JJ 6v6 tubes the amp came back to life.
After a lot of head scratching after I re-capped the amp I was thrilled to hear it fixed, thanks to AmplifiedParts.

Replacing tube constellation on a stereo amplifier - needed a dual rectifier. The plates in this one are much longer that the original 5Y3.
