In this video, we'll install a Hammond 1650HA push-pull output transformer in the 2006 Gibson Epiphone Blues Custom 30 amplifier we recently serviced. After replacing the power transformer with a Mercury Magnetics, this customer decided to go ahead and make this into the most rock solid amp we could make it by replacing the OT. We'll also dig into the power transformer and see if we can determine where the failure occurred.
