Tube Projects

This page contains some of the IC analog design projects that I have worked on. This includes Masters related work at RIT.

Champ Amp, My First Amp

This was my first tube amp experiment. It is based on a Fender Champ from the 50's. The Champ was designed to be a cheap practice amp. It features all-tube construction, about 5 Watts of power and tone control!  read more »

Magic Eye Audio Detectors


This project included a complete power supply and circuitry to enable a voice activated Magic Eye tube. The user speaks into a microphone, it is amplified by the triode in the 6T8A (the tube to the right of magic eye tube), then the signal is rectified and a peak detected signal is sent to the magic eye tube. Inside the magic eye tube, there is another triode which further amplifiers the signal and then drives the deflection grid in the cathode ray device. I will post the circuit sometime soon. I gave it to my Dad for Father's Day - what a useless gift.  read more »
