legally do 20W out at 100MHz. Somebody mentioned the 6146, which sort of
replaced the 807, 50 some years ago. It will do around 40W at 100 MHz, but
has nothing in common with the 807. Different size, and different number of
pins. I don't know where the EL34, or equivalent, comes in. I thought that
was a single ended audio tube.

In the 50s, when the Novice license began, they were permitted to use AM on 2
Meters. The Harvey Wells TBS50 transmitter helped fill that market. It's 807
final could provide 5 Watts input at 145 MHz. On HF it would coast at 50W.
