Re: Heath TX1 power --
The Heath TX1 used a pair of 6146 output tubes, those normally run 180
watts *input* power.
Modern transceivers (K3 included) are rated fort power output.
If one assumes a 67% efficiency (realistic) at 180 watts input, the
output power will be 120 watts - that is about what one can get from a
K3, although I do not recommend running the power knob to more than 100
watts to keep IMD under control.
Sooo - I don't think the TX1 will "crank out a whole more power" It
seems to me to be about the same.

Good question and answers here I did the same as don suggested up
till recently. I have a Heathkit TX1. I had no receiver until
recently when I got the RX1 to go with it. bit of a crappy reciever
but its still a fun to do the nostalgia thing. The TX1 will crank
out a whole lot more power on AM and CW than the K3 and it warms the
shack in the winter. Its not all DX and contests sometimes its fun to
get out the old and tinker. next up is 1930 era two tube push pull
UX-245 40m transmitter now were talking chirp!.
