The "combiner" idea is an interesting concept for the KPA-500.
"Combiners" are very common in solid-state broadcast transmitters and one of the
major advantages is "redundantcy". If you had 3 KPA-500's run thru a combiner
and running 1,500 watts output... even if one died then you'd still have
1,000 watts output. For serious contesting work,
the "combiner" sounds like a terrific idea. 3 KPA-500's x $2,000 = $6,000
which is close to what a single 1,500 watt solid-state amp is likely to
cost and with the multiple
KPA-500's you'd have the big advantage in that you're still on-the-air
with almost full power even if one KPA-500 fails.

Joe,
Why not stack 4 KPA500's and use a combiner!!!
