I've never seen anything made by Haydu in person, other than the orange-label 6700. I've never even seen a photo of a Vari-Count module. They might as well not exist.

Burroughs article is the direct result of a lengthy, heated email debate between Emilio Ciardiello and myself (with some poor out-of-the-loop Radiomuseum moderator stuck in the middle). Mr. Ciardiello had published another article dealing with all sorts of velocity modulation tubes, including beam switching tubes, and he had regurgitated the same incorrect Haydu origin mantra. He subsequently edited the content of this article enough that it is vaguely-not- incorrect, but he doesn't actually admit that I was right all along. The Haydu Vs. Burroughs article is basically useless and draws no real conclusions. Here's the first article dealing with velocity modulation tubes... http://www.radiomuseum.org/forum/vm_tubes_magnetrons_and_similar_devices.html He indicates the origin and dates of the Haydu ads in this article. I seem to remember somebody in the past telling me that there was another unrelated tube called an Inditron, but I can't say for sure.
