[AMPS] Recycling filament

[w8jitom@postoffice.worldnet.att.net]

I have to agree with Peter, I can't imagine a 723 being a "good 
choice" for an IC near strong RF fields. I  seriously question the 
carte blanche statements about bypassing ("do this, it always 
works").

But ignoring all that, why would anyone want to re-start the whole 
filament cycle if the power line just faulted for a few seconds? 

Cathode temperature would drop at the nearly the same rate as it 
takes to rise. If the line totally removed voltage for ten seconds, 
it would only require a ten second warm up to be back at full 
temperature.

Why recycle the tube for three minutes every time the power line 
faults for a second or two? That makes no sense at all, especially if 
it's just a quick "brown-out".


73, Tom W8JI
