Highly Modified 1967 Princeton Reverb Returned to (more) Original Condition

This video features a highly modified 1967 Fender Princeton Reverb that was sent to us for restoration to more original specifications. The procedure provided the opportunity to discuss several topics in detail: 1.) The design and implementation of Pentode/Triode switches 2.) Capacitor Time Constants and their effect upon tremolo speed (very basic discussion with analogy). 3.) DPDT switch theory 4.) Tremolo Footswitches.....does your Fender amp need one, and why? 5.) What is the purpose of Screen Resistors? In addition, we will open some birthday gifts from generous viewers and you will meet Mitzi, the latest addition to our feral cat menagerie.

NOTES: I apologize for the brief autofocus failure during a portion of the screen resistor presentation. I realize that 1967 was not "Pre-CBS" but the circuit design did predate their takeover.
