I had thought about that when I was about to order my K3 as a 10 watt
version (to start).  I turned my 746 down to 10 watts measured and my
unmodified ALS500 put out 140 watts with 10 watts in (500 watts out with 100
in).  That is what i intended to do until I could get the additional money
for the PA.

Amplifiers are not such that 100 = 500 so 10 = 50. Solid state at least,
look at the charts for the 2 meter amps for instance)  Doesn't work that
way.
