Re: Misleading Ebay Tube Testing Claims

Yes, I think that description is not too accurate.
I sell tubes on E-bay and A-Gon every so often, because I have too many, not because any dealers don't want them - quite the contrary.
I assume that the potential bidder knows what he is looking for and therefore provide as much relevant, accurate test info as possible - first through a 539C then through an amp at anywhere from 250-500+ plate volts for current draw at a constant -grid voltage. Now, is this an end-all and last word on how those tubes are going to test out in various other testers and amps? Of course not! Every amp and tester is different. Yes, power tubes through the more common suitcase testers will only give a relative comparison to each other at reduced voltage levels - so that shouldn't be used to state "matched" (that term IMNSHO has been abused to the point of being almost meaningless).
Not every E-bay/A-Gon tube seller is a schmoe looking to rip people off.
