Can someone describe the differences in these tubes please? Other than the different filament voltages and possibly controlled warm up time. What were manufacturers doing with these darn things? Thank you much. JH. :-)

Hello again,

Looking up the data sheets, these are essentially TV tubes. The exception is the versatile 6W6GT which can be used in low-voltage audio applications. Could be a fun little tube to play with :)

May your tubes be lively and long-lasting. Holy be thy heater.

  Yes yes, I see and read what you type. Maybe I could rephrase my question. The differing nomenclature, I have all except a 6dg6 and their internals look strikingly similar, in their data sheets they are all very close in gm, rp. Could they be the same tube but designated for different uses? JH

Ill check back with more if I can add anything with a little snooping, but the high voltage filaments were meant for applications like TVs and radios where they didnt have a heater on the transformer. As i understand it, youd use a combination of tubes to equate to 110v, so you could just wire the heater directly to the AC line.

So, the question is not so much what tube manufacturers thinking, but rather what kind of electronics were engineers designing, and what cost and servicing parameters and warranty could they offer a device. Tube manufacturers made many designs to-spec-n-order for applications of all kinds.
