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 ? Bob kb8tl at arrl dot net |

We on R.A.T. use those in keister-kickin' audio amps - how much? Would you
consider trading for other tubes? -- Gregg *It's probably useful, even if it can't be SPICE'd* http://geek.scorpiorising.ca |

Well, this is the second newsgroup where no one has told you how to test
them but has offered to buy them instead, so let me suggest a procedu - Sell the tubes to Gregg at a high percentage of the "tested" price. - Promise to take back the bad ones. - Count how many come back.
