Dissecting the HDR: The control panel and rubbing plate.
1. The heavy duty electrical tape is in fact "heavy duty" (and a pain in the butt to un-tape).
2. Steven had some "unique" building techniques: every time he would tape down a wire,
it would be the only wire; a new wire, a new piece of tape, stacked on top of each other.
It took a little "effort" to work through the tape.
3. The coil is a "caduceus coil", and I remember Steven having trouble with taping the coil to lie flat to the case/rubbing plate.
4. The potentiometers: 2 Radio Shack 10k-Ohm Audio-Taper Potentiometer Catalog №: 2711721
Steven would cut down the shafts to make them fit on the face-plate and have the knobs not too high.
5. The switches: 3 Radio Shack 125VAC SPST Mini Toggle Switch 3A Catalog №: 2750612
Steven use to buy the Radio Shack 250VAC 2P SPST ON-OFF Mini Toggle Switch 6A Catalog №: 2750324, that came with the colored slip=on tips (red, green, and white) But had purchased a bunch of colored tips from Digi-Key so he could buy Radio Shack's other mini switches when the 3 packs were unavailable.
6. The knobs: 2 Radio Shack 1" Molded Hexagonal Control Knobs 4-pack Catalog №: 2740416
Steven originally used guitar control knobs that were numbered 1-10; these "confused" people that didn't understand radionics "tuning" and "stick" reactions and were looking to set-a-date with two dials 1-10.
And trying to write instructions on how to get a "stick reaction", while tuning an HDR is difficult at best.
Unfortunately all I know about Steven's orders from Digi-Key were the Black Bakelite Boxes, the wire, and the light on the control panel. (there could be more)
As I come across and/or remember information, I'll post it.
