OK, so a while back I picked up one of these at a little antique/junk shop in Oregon for a couple of bucks. It's in an old REALISTIC box, but the tube is marked DUMONT in red lettering. I googled it and only found some Dumonts in green lettering. It seems this was designed for color TV's, but has been used in audio gear notably the HK Citation II.
I'm just starting to read up on tubes, so I don't really understand yet, but is it ok to put ANY 12v tube in the Sensation? Has anyone tried this tube?
I read the following from one source I found, would this be a problem?:
The only draw-backs to the 12BY7A are that it likes to pull a lot more milliamps than the usual small signal voltage amp types typically used in audio equipment (for current hungry colour TV CRT cathodes) so they will require a stiffer active tail load made from power transistors. (Even though considered small signal, the 12BY7A runs more like a power type). This, in turn, makes for a high voltage requirement.
