Upgrades: WAD 300B Parallel Single-Ended Monobloc Amplifier, Testing

In this video Nick takes us through his process for switching on amps that haven't seen any juice for a long time. Before running any signal through the amp and potentially blowing components, a quick once over with a multimeter should show any nasty surprises before its too late!


First listen of the amps revealed some of the inconsistencies seen from the circuit and the humbucker pot at times seems to add as much hum as buck, but the warm musical character of the 300B valve's is very much there waiting to be brought back to life. Stay tuned, in our next video we'll decide on what to upgrade/replace, then on with the build!
