Dual Rectifier Repair – Mesa Boogie – Ampworks, Newark

This Mesa Boogie Dual Rectifier Repair is one of the more unusual problems I’ve come across. The Mesa was brought in with very low (and unpleasantly distorted) volume and blowing fuses. I tracked the issue to the output circuitry and checked for all the usual failures with no result. The output transformer looked to be the faulty component but the issue turned out to be a faulty component that was loading down the 4 ohm input with a low impedance. Component changed and the amp springs back to brutal METAL life!!

UPDATE 2016:
Mesa Boogie repairs are among the most difficult jobs to do, partly because of the complexity of the amp (which makes for a fantastic product) but also because they design their PCBs in a way that aren’t very friendly to repair. I’ve done many mesa boogie amps though (you can read about others here) and they are always worth fixing!
