Paul -
Those two pin connectors are one of the most "unobtainium" items in the
4 & 7 Line. Even Drake gave up on them, and offered a small metal plate
with an RCA phono jack on it and two holes that matched the mounting
screws for the two pin connector in the AC-4.
If I didn't have one, I'd seriously consider doing the modification with
an RCA Phono jack like Drake did. And I'm one of the worst when it
comes to preaching the "keep it original" mantra...
Once in a great while one of the two pin connectors will show up on E*
for an exorbitant price. The last one I saw a few years ago went for
over $20...
The pins are 0.093" in diameter. Some have made a connector from #11
solid copper wire. Various schemes have been tried with plastic and/or
epoxy to build up a connector body around the two pieces of wire. #11
wire is 0.0907", and tinning it with solder should make it just about
right. I would tin it to ward off corrosion. Unfortunately, #11 is NOT
a common size (to say the least!). #10 is 0.1019", which is a little
large, and is probably what the "plug builders" used. I don't know if
that is large enough to damage the female connector or not. The pins
are spaced 0.350" c-c. A better choice might be some 3/32" dia (0.0937)
brass tubing from the hobby shop. It would give a more reliable
electrical connection to the wire. Think that's what I'd do.

Anybody have a part #/source for a VOX connector for the AC-4? What
else can you use to make a relay cable? Going to try the 'B' line on
one of my amps.
