> 
> Just to make sure I was correct, I looked up conjugate match in one of
> my textbooks. A
> conjugate match exists when reactances are cancelled and the resistance
> of the load is
> matched to the internal resistance of the generator. Under these
> conditions, the power
> transfer is maximum. However, since the resistance of the load and
> generator are made
> equal, the same power is dissipated in both thereby limiting the
> efficiency to 50%. If your
> amp is over 50% efficient, then it can't possibly be conjugately
> matched. As I stated earlier,
> we don't design amps for maximum power out. We design for desired power
> out whilst
> keeping the tube in the linear portion of it's operating range.
