DO the napkin rough math. P=IE ... this is still on the amateur exams --

Good evening, GB.

Yeah, I know all that, I didn't really need to be talked down to ...
but older tube type rigs have filaments in all the tubes that consume
current too, and I don't remember what the current consumptions for
many of them were, and so I can't, as you say, "do (no, I mean DO) the
napkin rough math".

I keep forgetting that on Usenet one has to be good at wading through
all the smart-ass to get to the real answer to one's question. Your
"other devices drawing current (usually less than 1 amp)" is the
answer I needed, if it's accurate ... thanks.

The current ratings for most transformers in these tube rigs are under
3 or 4 amps at 6.3 or 12 VAC - which less than 1 amp at 110 VAC.
