[ICOM] FW: Info on Icom PS-55 Needed

[Gary Fiber]

So far as I remember the AC for the PS-55 did indeed go through the 
IC-735 power switch. The PS-55 6 pin connector has 6 wires, 4 are the DC 
and the other two are the AC. Some over the years did wire a separate 
switch into the PS-55 since there was no other way of powering up that 
supply with out connection to an Icom product or installing a switch or 
at least jumping the 2 AC wires together.
