Miro, OK for "MnZn" it was my tipomistake
Please read my post again.I only and only talked / wrote about the voltage and
power of the peaks.At the peaks,the toroid and the coils are loaded with this
voltage and power. The dog is buried there. This is the maximum and real stress
that the choke experiences at the peaks.The arcing between wires is always on
the peaks.
PA - Tube with 1900 volts on Anode/ 0.5 A plate current (DC) when the PI filter
is set to max output power on 3.65 Mhz..
LOAD - 250 watts non-inductive load up to 3 Ghz on a solid radiator (I had to
pause so as not to blow it) is heated to 80 degrees Celsius for 30 seconds
Nonstop test.The Choke NO - it remained relatively cold.
KEY DOWN ON CW is very good test....Nothing less, nothing more.. I can't say
Best Regards ! Thanks for the Comments !
