In appears to be an external input for a phono or FM tuner. There is a white wire that looks to be connected at one end. It's all the was to the right side toward the front. If it is hanging loose cut it off as it is connect to one side of the AC plug and is dangerous.
Looks all pretty original so you'll need to replace a few consumables. The two thingies at the front of the chassis that have the metal strap holding them on. Those are three electrolytic capacitors (2 are in one of the units) that after 76yrs are shot and could cause damage to other expensive parts.
Also there are about 12 other capacitors (there about 1" long and 3/8"in dia) that should be replaced for reliable service. Should cost about $20 in parts.
If you are interested I'll dig up a schematic and make up a list of the proper values.
Found a good copy on the schematic here:

It's on pg 103-104. You not being a technical type it may not make much of any sense to you. Basically it shows where all the parts are and how they are connected together along with how the make adjustments to critical circuits.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
