Secrets of the Fender "Twin-Amp" - Uncovering & Restoring a LOST CIRCUIT!

In this video, we'll use all our amp archaeology skills to uncover the original LOST CIRCUIT of the early, 1953 tweed Fender "Twin-Amp". The Twin Amp was Leo Fender's first 212 combo, and the first time he'd used separate Bass and Treble controls in a guitar amplifier. It also harbors a secret. The first iteration of these amps had a different tube compliment than the earliest published 5C8 schematic. The 5C8 schematic has a 6J5 tube before the tone stack, while the earlier amps - the first couple hundred perhaps - had all 6SC7 tubes. Without a schematic to go from, we'll have to examine the evidence closely and try to figure out what the original circuit was after decades of services and mods.
