I have manuals on the 50128 and 50128A.  But in typical TM fashion, they are
mute when it comes to exactly how the Interphone Amps were actually used.

Robert,
	I have both manuals too but only have hands on the water damaged 'A'
version right now as the other is back in the, """Shudder""" , heap, in my
garage/shop/wallow. What they say in the darn manual amounts to 'Whatever
you work out in the first vehicle that works will be the standard.'
Also...they say "vehicles and craft" which points to squidly use too as well
as terrestrial endeavors for the interphone equipment.
