Summary
Summary
At the age of 21 I built an all-tube home theater system (except for the DSP stuff). My friends in college called it "Frankenstein," because it look absurd sitting in the corner of my college dorm room. It consists of 5 class AB tube power amplifiers, tube pre-amps, and a Dolby 5.1/DTS digital signal processor, for a total of 27 vacuum tubes. Each power amplifier is capable of over 400 watts peak output. All of the equipment is mounted in a 7' tall WW2-surplus equipment rack.

Caution! High voltage. Do not attempt to build anything shown here unless you have taken proper high voltage training. The high voltages present in these tube designs are deadly.
