[ARC5] ARC mini-bananna size?

[J Mcvey]

You had me going for a minute!Unfortunately the IF can plugs are smaller than the ARC5 tx jack.I measured across the pins at the top of the "U" pattern on the ARC5  tx and I get 1.5 cmThe IF cans distance between theses same pins is only 1 cm as are the SCR274 tx.

This is why an ARC-5 transmitter won't fit in a SCR274 rack. The ARC-5 tx plug diameter is slightly larger.I don't know why it's so hard to find a MT-71 rack!

 If you have a junker -A model SCR-274-N, ARA or maybe AN/ARC-5 receiver, you have the makings of three plugs for the back of the ARC-5 transmitters from the plugs for the RF cans.  Plus three for all of the other model radios from the plugs for the IF cans.  You have to add the center pin.

Pomona used to sell several variants of mini-banana pins.  What you have to watch out for is the mounted length.  As all six of the above mentioned plugs are mounted from the top, the RF plug pins need to be a little longer than the IF pin plugs.

I bought some 'miniature bannna plugs" that  were 3.04 mm diameter, but they don't mate snugly with the ARC jack.
Must be some odd size -?


What is the correct size and where do I find them?
Also,I would like to find ( at minimum) the male connectors for the ARC-5 type transmitter ( larger than SCR-274).
Better yet, a MT-71 tx rack...
