[Milsurplus] ARC-38 control head connectors

[Ray Fantini]

The heads for the ARC-38 and 38A are almost identical. The only difference I have found is the sticker that's placed over the mode control for SSB and a couple jumpers on the back of the control are changed. All the channelizing RF/AF gain and other stuff is the same. Question: I have only seen couple 38A transceivers and heads but was there any ARC-38A that were produced as a 38A or are all 38A transceivers and heads re worked ARC-38 sets? And was it official policy for RCA or whatever contractor who re worked ARC-38 to ARC-38A sets to paint over the Collins logo on the front of the radio? My ARC-38 and 618S1 both have Collins logos on the front but the couple junk ARC-38A sets I have for parts are painted over. One last interesting note is that when the radios were converted to "A" sets they stenciled on every module in the radio "modified for SSB" including things like the receiver audio amplifier, relay and servo amplifiers although in all three radios there is no difference in any of them.
