Are there any sensibly priced switching supplies (even surplus) that are small
and light, that could power some of the QRO tubes
with high current filaments? Would, say, a 5v, 30A switcher which could
power a pair of 3-500Zs, be economically
competitive with a 5V 30A transformer, and even if it is not directly, it might
still be worthy of consideration
if it was small enough, and light enough to significantly lower size and weight
in an RF deck?
Would cold start surge current be a problem for switcher implementation for
filaments?
