Thanks John but they most definitely are not DIN plugs on the TE.
It really does look like a 7-pin tube socket (with brown phenolic in
the center and all) mounted to the back of the amp.  The plug that
TE provides is a circle of straight pins mounted in a roughly 1/2"
dia plastic carrier.  You solder your wires to the back of these pins
and no shell or cover for the backend of that plug is even provided.
It's real goofy.  Cheesy.  Non-robust.  I did find that if you needed
all 7 pins (besides the keying line and ground, the others are remote
control signals for adding a remote front panel to the amp), a true 7-pin
DIN socket would fit the same hole in the amp's back panel.  So, you
could retrofit with a DIN if you wanted.  I never plan to add a remote
front panel so in an attempt to standardize all of my PTT connections,
just fitted the RCA jack instead.
