I see you are located over the pond so will not be infringing the UK frequency control re 35Mhz.
I am assuming by old you are referring to the older three pin female sockets with the battery and servos using a three pin male connector? You can use modern kit with the Rx but will need a conversion lead to match the sockets on the tx to the modern plugs.
Trying to remember my flying days equipment I believe the battery socket was marked as such.
The connections polarity wise were the same with black negative, red positive and white signal wire. The black wire was always nearest the case bottom edge with the red wire between the black and white wire.
The battery connector did not have a connection to the signal wire so if a servo does not work in a channel it could be that is the battery connector socket.
I hope this helps but please ask if you need further help

Live long and prosper
