[Milsurplus] LS-3 question

[W2HX]

Hi all,

I have an LS-3 that I plan to connect to my BC-312. The 312 loudspeaker jack fits a PJ-055B (1/4"), however the LS-3 has a smaller diameter jack. A PJ-068 fits fine into the LS-3, however the PJ-068 is a 3 pole connector and I only need a two pole. What is the right designation for a plug with the same diameter as the smaller PJ-068 but with only two poles? Or was the LS-3 expected to just use two of the three poles of a PL-068?
