So here is how I wired it.
One end of the Ac line, a o.o4 capand one end pilot lamp to one end of ,40 ohm 10 watt resistor. The other end of the 40 ohm resistor to one end of the resistor200 ohm which is connected to other end of pilot lamp and ground lug? of 35z3 tube. The other end of 200 ohm resistor to 35z3 tube lug.
When this was brought up in variac the pilot lamp glowed bright then went out.
The 35z3 tube got really bright.
No sound but end of 40 watt resistor started to smoke. Both resistors got really hot also.

I made sure no wires were touching .
Did I wire it wrong?
Thoughts?
