[time-nuts] Any reason not to use one power amplifier and splitter for distribution amplifier?

Good point.  I take pains with power supply design and very rarely 
have problems with supply noise in practice, but you're right, taking 
the output from the emitter winding should help reduce PS noise 
coupling if it were a problem.  I foresee no countervailing adverse 
consequences, so that should be considered the preferred connection 
for the two-winding variant of the circuit.

Best regards,
