First rule is to always discount whatever Mark Jenison says...

I can take a look tonight on one of my spare ones to verify.

They are already available on wiretap. The one on wiretape shows .68 ohms
also, and I think it says +63VAC, but I can't be sure. I got those numbers
from David Shuman a long time ago. I believe the +6.3VAC is for the heater,
and since the tube is the same as the WG6100, my guess is that +6.3VAC is
correct (which would imply that maybe a larger resistor would be called for;
I'll verify for you tonight).
