Just run the Orion "Amp Key" line to your Ameritron's relay or key line,
whatever it is called. The Orion is designed to bring up the amp key line
early enough to allow the amplifier's antenna relay to transfer before
transmit power is applied. Experiment with the best "EXT T/R Delay" on the
Orion to keep the amplifer's relay up during words. You will lose QSK with
this amp but it will work fine.
