Greetings from a lurker --
Dick has an interesting idea here and I enjoy pretending that I know how to
play the numbers g so here goes...
Let's use the 200w figure with a car amp with a bridge amplifier powered by
the car's 12v battery, and for the moment we will neglect the losses.
The amp's
Speaking of AM Transmitters, does anyone have a source for plans to build an AM
Transmitter for 75 meters in the 15-25 watt range?Thanks.

Have you considered using a car audio amplifier in a cathode modulation?
If possible it could avoid finding another transformer that would stand the
higher voltage and current in a plate arrangement.
I give this some thought every time I'm in my friends car audio store.
But, being one who always

A transmitter like the DX-60 puts out about 12W of carrier in AM mode. It
uses Controlled Carrier modulation and does not require a modulation
transformer
Don't you just hate it when someone replies to your post with a different

PA-100 with 4 6L6's
in Push-Pull, that is being converted into a
modulator for a pair of 807's, the RF deck and
power supply are done.
Have Fun
