[Elecraft] KPA500/KAT500 paired with AL-1500?

[Jim McDonald]

I key my KPA500 through the aux cable from the K3 and my 87A through my
microKEYER II.  Only one amplifier is powered on at a time.

I key the KPA500 and Titan in parallel, but only the one that gets RF
transmits. :)  I can do that because the two amps use the same keying logic
and the amp key line feeds a transistor.
