Well, if we're volunteering other people then how about Alan Wolke (W2AEW)?
Agreed. He jumped to my mind, as well. If I had a question about an old analog Tek scope, I can't think of anyone better suited to answer it, and he has demonstrated that he enjoys sharing his depth of knowledge.
I can't say anything bad about any of the people mentioned here, as they're all very knowledgable and generous with their knowledge, but few others seem to be as expert in the specialized area of vintage analog scopes.
OTOH, a mass market show probably won't get too deep into technical details. Availability, willingness, and other non-technical things will certainly play into the producers' choice. And face it, though I'm unlikely to catch the show, if I do, I might be squinting at the rack of glowing test gear in the background more than the person doing the talking...
