cooperman | Tech: Vacuum Tubes for Fender Champ amplifiers (19) | RE: Tech: Vacuum Tubes for Fender Champ amplifiers | 01 Sep 11 |
Interesting (and annoying 'cos it happened to me!) modern tube amps are more likely to fail in the circuitry than old ones. The heat from the tubes dries out the tiny solder joints on the PCBs that they mostly now use. The old amps had discrete components that were wound round posts then soldered. Much better in this application!! |
