However, for their vacuum relay switched amps, like the 91b and 99, you
can run the same TT keying loop as you would use for a TT amp, and the
Alpha's switch beautifully that way. The web site method is specifically
for the PIN diode switched amps, I believe. My '99 runs great with the
TX EN, TX Out loop.
