Vladimir Zworkin's 21CT55 Restored and On Display

[Kirk]

I have the one they built to plug in where the ballast tube goes- its the same circuit as the one that is "built in" to the 21CT55 that we have running. It came with a hand-drawn schematic, done by David Neegard, the 87 year-old Engineer from RCA.

I will dig it all out and hook it up to a working CT-100 chassis that I currently have on the Test Jig.

Once I know it's OK, I would be happy to share the info with whoever wants it.

Stay Tuned!
