This Thursday Barrie Gilbert is giving a talk at my local ham club TERAC, and promises to
bring some rare and exotic tubes. Im looking forward to it, and I will report the rare
stuff he brings to the talk. We are all encouraged to bring our favorite tubes, I'm
sure there will be some Emiac tubes there. Im bringing a 3BP1, a 3" CRT. I got a
pair of these new, in the original sealed government boxes from 1945. When I opened them,
I swear the air inside was from 1945, I felt like Indiana Jones opening a tomb.

No - modern high power transmitters use redundant hot-swappable
amplifier modules in quantity. A few manuafacturers may still make
tube based designs, but they are getting long in the tooth.
Hell, even Eimac is pretty much gone.

The last time I saw some of those big jugs was last October, while visiting a
friend (somewhat older than I am, in his late sixties or early seventies),
and who knew them well. He had an assortment of them around, and was
talking to me about a bunch of them being destined for some sort of a display
exhibit...
