Fender Ultimate Chorus Switch Replacement
Tuesday, November 4th, 2008This post is not a video, just pics. It is a result of recent emails with a guitarist that bought an amp and wanted to switch out the AC off/on switch.

Fender Amp Power Supply Problem
Wednesday, June 18th, 2008This video found on YouTube is a perfect example of a filter cap problem. On solid state units like this one, through vibration and assembly techniques, components can work themselves lose from the circuit board.

Tube Amp – Bent Tube Pins

Glowing Output Tube Trouble

If you experience this in your amp, turn it off immediately and take it in for repair. Simply replacing a tube may fix the problem [...]
