fender prosonic output transformer

[Leo_Gnardo]

FWIW, I replaced the OPT in my '76 Pro Reverb with a Pro Sonic OPT which was a bit bigger and more versatile (4-8-16Z). Much better bass response.

+1 more now. I always recommend to those who have amps with the A6A transformer to replace it. It's the one Fender transformer I've replaced more frequently than any other, due to failure. They're in Pro Reverbs, Vibrolux Reverbs, Bandmaster, Bandmaster Reverb, maybe some others. Usually I use a universal Bassman/Super-Reverb 4/8/16 from either Magic (Ruby) or Hammond. Similar improvement to using a Pro Sonic OT I'm sure.
