Ed, and Bill, 

My original question was regarding the 6LR6, which is quite different
from the 6L6. The 6L6 takes 6.3V and 0.9A  for its heater, while the 6LR6
uses 6.3V and 2.5A. My source (the Electron Tube Locator, by George
Fathauer) only gives the heater characteristics, and pinouts. Nothing
else. The 6LR6 has 12 pins, and is a pentode. The 6L6 has 8 pins, though
it is also a pentode. the 6LR6 costs $35.00 from AES, while the 6L6 costs

This is all getting very confusing to me. I just really wanted to know if
I could use the 6LR6 as a triode (I now know how to hook it up, i think.
G1 is biased, G2 connects to plate, G3 connects to cathode. ?)

I'm not looking for much performance out of this tube, just 1" or 2"
sparks. I also have an 811A I will be using in the future, so my interest
is not in just getting the bigger sparks. I want a -really- small VTTC.

At that, I may want to try to wind this extremely small HDPE form i have
(about 1"X5") with hair-thin wire....
