Video Description
This video records the challenging restoration of a 1969 Fender Princeton Reverb which was badly burned in a fire. The chassis was rescued by the owner, who hand-built a beautiful, original-looking replacement cabinet with a nice Jensen speaker and new Accutronics reverb tank......then, very sadly, it was turned over to a local "technician" who proceeded to mis-wire it badly, with several short circuits, missing wires and connections, and improper component values, creating a dysfunctional nightmare. In desperation, it was sent to me for repair.....and presented one of the biggest repair challenges I have ever faced. This video follows the step-by-step elimination of (hopefully) all the previous mistakes, resulting in one of the best sounding PR's I have ever heard. I hope you agree :) In response to viewer requests, I have focused on relating schematics to actual circuits, given detailed explanations of why certain repairs work, and thoroughly discussed pertinent tube amp circuitry details......all in an attempt to maximize the educational content of this video.
