Amazingly Original Pre-War OAHU Amp Gets a Tune-Up

As a change of pace from giant Fender Twins, I thought you might enjoy joining me for the evaluation and repair of an absolutely stunning pre-war Oahu (Valco) amplifier. We inspect the amp thoroughly, inside and out, discuss the very early and unusual tube set and the evolution of rectifier tubes, then begin a step-by-step repair of the somewhat troublesome circuit utilizing a typically inaccurate Valco schematic. Once the repairs are completed, the amp is subjected to an audio test to demonstrate its surprisingly good tone. In addition, we have an exciting announcement around the middle of the video that will be particularly interesting to loyal viewers and don’t miss it !!
