Heath SB-200 on AM

[Glen Zook]

About 300 to 350 watts input maximum with "normal" AM
(up to 500 watts peak with "controlled carrier).
Output is about half.

Frankly, unless you are running something like a DX-40
or other low-powered rig, it isn't worth the trouble!
Linears are really inefficient on full AM (actually,
SSB is a form of AM, but when most people think of AM
they are thinking of the full carrier, double-sideband
transmissions).

If you are running a DX-100, Apache, or similar 100
watt output plus AM transmitter, you won't really do
any better with the SB-200 in line.

Has anyone used the SB-200 for AM and if so how hard
can you push the rig before the tubes melt? What
output power should be expected
