According to Mr. Smiths web site the
correct battery for radios like the BC-474 and GRC-9 and the
like is a BA-48 that provides 1.5 and 90 volts, I do not know
the name of that connector but it is a four pin female
connector that’s used on that battery pack. The battery packs
that I will be building for MAB/DAV use is a five pin female
connector like in the picture. They had to provide a bias and
screen voltage so they needed an additional pin.
The plan at this time is to build a battery
holder that will fit in the same size space as a BA-48, easy
to see how it was used on the BC-474 but not at all apparent
on things like a GRC-9 because they must have just been thrown
next to the radio?

It looks similar to the batt connector
for the PRC-25 or -77 from a BA-4386. I found a source at
Haney Electronic Co.

OK smart
people, what is the proper name of this type
old socket? It’s a five pin socket that would
have been used on a battery pack. Building up
a couple battery packs for MAB radios and need
more of these. Also similar to what’s used on
the battery pack on the BC-474 radios
(receiver) except that’s a four pin missing
the one loan top pin.
