"An Electronic Musical Novelty: Individual Oscillator for each key permits any number of notes up to a full 66-note keyboard." by Jim Kirk.
This LOOKS like a 1950 synthesizer, it uses tubes, I'm sure it will be of interest to all early synth and electronic keyboard folks, and it gives the circuit and power supply circuit you'll need to do the job. Uses a 6SN7 tube, and 5Y3 and VR150 in the power supply."
Update via metasonix in the comments: "I've seen that article. It's an organ, and a very primitive one at that. (Electronic organs were very rare and costly at that time so it had novelty value.)"
