Hi Rich !
HEATING VOLTAGE TL922

? A new world record!. At such a fil V one would receive 4% of the
normal emissive life. .
Looks like this is so far off that I guess the swaped wires
are not enoght to reduce the heating voltage. Do you have
a guess what kind of R I need to get into a better area ?
I don't want to play try on error and I am not quite confident
how to calculate the two (?) R's .... .
tnx for update, Helmut. Congrats on new world record!
... thanks.
