If the keying circuits of the amps in question are to a logic input, the 
current draw is quite small. That is true of both Elecraft and Ten Tec 
amps. It's also true of most (all?) Alpha amps, many of which were 
designed by K4XU, who designed the Ten Tec 425 (the original Titan). In 
the late-'70s vintage 425, it's the base of a transistor.
