Carl, the problem is that many of these old bottles are gassy.
There are some techniques to rejuvinate them, like reduced plate voltage to
burn off the gas.

Subject: [AMRadio] Difference and use of Eimac TH and TL tubes
What is the current feeling about the use of those old Eimac jugs? 100T,
250T, 304T, etc
If memory serves me OK the high mu TH was mostly used as a RF tube and the
low mu TL as modulators. BC-610 excepted of course. What are the trade
offs between the 2 versions as modulators besides drive requirements?
