<< Hi Jan!
The 250 W is about the point where the plate starts to show a dull red
glow. If you can get a copy of the RCA technical manual TT-5 "Transmitting
Tubes - to 4KW Plate Input" it has all the specs. Reprints are available
Antique Electronic Supply of Tempe Ariz.

The 811 is a great tube for a VTTC but you guys better take another look at
TT-5 and the 811 specs. The max plate dissipation is around 60 Watts. The 811
is just a big 807. They make great triode PP stereos. :)
