Yes. That was kinda what I figured too.

The pair of 803s will operate within specifications at 350 watts input each. Output will be 
slightly more than 400 watts for the pair.

That "Navy-rated 125 watts output..." means, "Tune it up into an antenna, put a brick on the 
key, and come back in a month or so and it will still be outputting 125 watts." ;-)

A pair of 813s isn't all that much better at the same voltage: 2KV.

Funny thing is, both are rated at 125 watts plate dissipation. The 813's plate dissipation rating 
is actually closer to 250 watts, though.

Anyway, it is fun to speculate.

I don't understand why more hams didn't jump on the TCM. It would have been a perfect ham 
rig for CW. It is small, it is VFO controlled, it covers all the main ham bands, its power 
requirements are reasonable, it is very stable, keying sounds very good. Maybe there weren't 
very many of them made. I dunno. It is a really neat rig.
