Svetlana makes a lot of big power tubes still to this day and they are good
quality. RF Parts carries them:
Beware some of the cheap "chinese" tubes. I got two and they literally
fell apart in my hands since the glue used to hold the base and top
terminal was not designed to withstand heat :-p Once i glues them back
together, they just arced and blew up.... I like Svetlana! The people at
RF parts can help you be sure you get good ones. Svetlana's websites seem
to be forever down :-(
RF Part also sell all kinds of other goodies!

Tubes of the kind you'd need for that kind of test equipment are easy
to find at reasonable prices. Quite a few guys have good stocks on hand
and have web pages. Antique Electronic Supply is one example.
