Incredibly impressive work! As an owner of the Daystrom CA-1630, New London 901A and RCA WT-100A, I would be proud to have your piece in my collection!

Hi Mark, I really appreciate your thoughtful comment. Yes, the CA-1630 is indeed, very impressive! And colorful too! :) It illustrates that there were some excellent laboratory tube analyzers back in the day. ---Thanks!

You might have titled this article, "What if Weston/Daystrom were still making tube testers?" The layout is reminiscent of their CA-1630. Your engineering, is however, far more clever, like HP. The use of a square wave signal with synchronous rectifier that excludes leading and trailing edge transients is a superb piece of thinking - very innovative!
