I have a c1950's RCA combination unit in working order. It has jacks
for external speakers (which have I do not have) which will accommodate a
three pin plug, in an equilateral arrangement on the back. I want to connect
other speakers to these jacks but I don't know what the pin assignments are.
Any help or suggestions would be appreciated.

You will need someone who is knowledgeable to trace this out for you and
determine the speaker impedance, if an external output transformer is
required, and ect. This is something that requires some base knowledge of
the type of receiver you have.

You can also try to go to one of the antique electronics sites, and post the
make and model number, in case someone will know off hand what you require
to do what you want.
