Looking for data on an Eimax Y-685A


 
Edited

edit: obviously I'm an idiot and didn't realize the typo in the title... Eimac not Eimax... ?

Hi all, wondering if anyone has any data on this tube? Potential candidate for a 23cm amp. This came out of a resonant cavity in a 100watt signal generator (this specific module was good for 400-1000MHz). Can't find any data on it, looks similar to a Y-503 but not quite. Have searched through a bunch of Eimac catalogs and found similar planar triodes but not this one. Would like to have some concrete data. Anyone familiar with this?

Thanks! 73
