Testing ceramic tubes
 

Acquired about a dozen 8122 ceramic tetrodes (400 Watt dissipation, 500 Mhz
max) pulls from a broadband EMC amplifier. I have no use for them other than
trades or ebay.
Anyways, I'm thinking to test these things for emission I make a socket
adaptor from the 8122 to something octal that my Hickock tube tester might
deal with say a 6146 and test it as such.
Won't know pass / fail but at least I can get an idea if they are all about
the same results and weed out any duds.
Anyone ever try such ?
