It is used in amps such as the Fender Champ and most of the early Fender Tweed style amps. examples are the Tweed -Princetons, Harvard. In these amps do not be tempted to use NOS ( New Old […]

The output valves , the rectifier, and ECC99’s all get especially hot ! Â My most recent burn was off the little output valve in the picture above, the EL84 output pentode The first basic question is how often to replace
