If it was 50 per cent efficient, at 100 watts, then about 15 amps.
If, say, class C at two thirds efficiency, then about 11 amps.

Subject: anyone know what the current draw is for TMV7A on high power?

Hi, all.

Does anyone know what the old Kenwood TMV7A draws in terms of amperage when 
transmitting on high power?

I looked on icanworkthisthing.com, but the manual there omits the 
specifications section.

I would suspect the current draw on high power is about 12 or 13 amps, but 
am not totally sure.

I'm getting packet radio set up here, and am trying to decide whether I can 
use the 7A for packet with my RS35 power supply, and the rigrunner, or 
whether I need to give the old 7A it's own separate power supply.

Currently, my rig runner and Astron RS35 powers my TS590 and my TMV71A, plus 
a few accessories, but obviously, everything is not operating at the same 
time.
