FWIW, that module was for 1/3 of the 3 phase stack in a Continental 816R
25KW FM xmtr. B+ is 9KV at up to 4 amps DC, but I'm sure they have more
headroom than that. Considering the premium Continental has to charge
for emergency parts, their real cost for the module was probably less
than $100. It was an International Rectifier module.
In fairness to shunt R&C fans, the old stack ran fine until a roof leak
dumped H2O on top of them while energized. Bang!
Hi, John. Don't forget to wear your proton repellant & sunscreen out
there. Love your always educational messages.
