A friend of mine in Canada is into designing and building tube amps using pre-octal triodes. In payment for a really neat Canadian Stromberg-Carlson 694 table radio he scored for me, I have been rounding-up 10's and 10Y's (military VT-25's) for him.
My Triplett 3444 gm tester, plus a couple Triplett emission testers I have, show different plate and bias settings for 10 and 10Y tubes. I assume the 10Y will take a higher plate voltage and have a higher RMS wattage in an output circuit. Am I correct in this assumption?
It would seem that the obvious place to go for this information would be a tube manual, but my RCA manuals make no mention of the 10Y. Any help you can render would be greatly appreciated.
By the way, those 7.5-volt tungsten heaters really light up a room!
