[Heathkit] Suggestion for legal limit AM amp (was Heath Warrior as an AM amplifier)

[rbethman]

I have used a DX-60 with the WC3K mods to audio, and to indicate over 
modulation.

The only WC3K mods I haven't done are to add 160, or the PTT one.

I have used it to drive the LK-500ZB, (Pair of 3-500Zs).  I've also used 
a TS-930SAT to drive the same amp.  I've gotten great reports.  It is 
simply a matter of keeping the power into the LK-500ZB within the limits 
it can handle.  I do NOT use compression, and monitor with an SM-220.

Works quite well.
