In this video we will document the repair of a 1966-67 Fender Blackface Super Reverb circuit. As delivered, it had some serious wiring issues and worn-out tubes, including a 5U4 rectifier, rather than the proper GZ34. These problems allow for a discussion of repair theory as well as demonstration of the relative performance of the 5U4 vs GZ34, both with and without a Current Limiter in series. A demonstration of tremolo speed reduction is also provided. As usual, an audio demo is performed, including each of the effects......tremolo and reverb.....at various levels. We hope you enjoy it.
