Joe -
Not a problem, I think we're talking semantics. There are three wires that come out of the bottom
of the "can". ONE goes directly to a ground lug on the gearbox rear panel, and is the ground
connection for the PC board. The other two wires are the Red and Green, Vcc and Output. The
"other" wire comes out of the side of the PTO where the can meets the rear panel of the gearbox.
This is the RIT lead, formerly the FSK terminal.

I don't want to start an argument here but I have 2 TR7s and 2 TR7As
and on all 4 of them there only 3 wires on the PTO. Any time there are
spare parts on ebay I
usually buy them. I also have 3 loose PTOs and they all only have 3
wires, no ground. As I said earlier, the later TR7s have a copper
grounding finger on the bottom of them
that contacts the chassis when the front panel is rotated into place.
This is the same finger that is on the up converter and translator boards.
