[Milsurplus] Interphone amp, 12V, CMX50128, contr xyz41

[WA5CAB at cs.com]

As Miike said, it's a TCS accessory, for crew-served vehicles with interphone 
systems.  Used in LVT's (Alligator) that were equipped with the TCS.  I've 
supplied a couple for that purpose, one in an LVT-2 and I forget where the other 
one went.  But used by USMC.  The somewhat similar RL-5, 6 & 7 were the 
aircraft ones.  There was also a CMX-50128A, almost identical.  If the one you have 
has a dynamotor on it, it must have been in service as for some strange 
reason they didn't ship with the dynamotor.  At first glance, they look like the 
ARA or either of the RAT dynamotors would work but they don't because the pins 
on the dynamotor plug on the back deck don't stick up high enough.  And there 
is a dynamotor that has been showing up on eBay for the past couple of years 
that looks like it should fit but doesn't quite.  Although I adapted two of the 
amps to use them.
