[Elecraft] n00b Amp question

[David Bunte]

Richard -

There are probably more technical responses than this, but I think the
simple answer is that if you have a 100W Solid State amp, and drive it with
100W you will likely either destroy something, or the system will self
protect and shut down. I know that with my K3 and KPA500 combo, I get 500
watts out with about 28 watts from the K3... if I raise the output power of
the K3 to a bit above 30 watts (maybe 32 or 33w), the amp 'faults' because
of excessive drive, so my 500 watts amp gives me 500 watts when driven by
an appropriate amount of RF. If it is additive, I am not aware of it.

I believe the answer is somewhat different if using a tube type amp in a
grounded grid configuration.
