Gene and the Group,
I have one of these as well, came along with the duplexer.:

Thanks for the nomenclature, Dennis. This should eliminate the CX-4656,
and power two PRC-77's from a single source, including 117 VAC. I'll
retrieve this stuff from storage. I should have at least on extra
PRC-77 or equivalent, like a 628K1.
If you really want to play with field phones, I have a small collection,
including an SB-22. I never thought anyone cared. :-(
