Very straight forward to use a tube based amplifier. I ran an AL80A for
a year with the K3 before I took the expensive leap. RF out of the K3
into the amp - out of the amp into a tuner - out of the tuner into the
antenna. A PTT line from the K3 to the amp. That is all you need.
Be sure to turn off the K3's internal tuner, if so equipped. Be careful
about over driving the 811A tubes. That last statement means _READ THE
INSTRUCTIONS_.
500 Watts is 500 Watts, regardless if it comes from some old inexpensive
tubes or from a very expensive solid state amp. Don't fall into the 700
Watts trap. The difference of an additional 200 Watts will never be
noticed at the receiving end.
