A few weeks ago, after powering up my 67’ Fender Super Reverb, a nasty crackling/popping sound could be heard emanating from it which lasted about five seconds or so.
After this event the reverb ceased working although it would still play otherwise.
I tried a tube exchange, the 12AT7 reverb driver, but no luck.
I suspected that the reverb transformer finally gave out, after almost fifty-six years, but I needed to trouble shoot the condition to be sure.
Some of you might be familiar with ‘Uncle Doug’ who has a YouTube channel that covers amplifier service.
He had an episode that included just what I needed and I was able to determine that the primary of the transformer had an open winding.
A replacement was procured, which arrived late yesterday, and I just completed the installation.
The amp is now back up and running again thanks to Uncle Doug.
