Phonoland

First time posting....
I've recently purchased a RCA Victor 1VF306 Console at a local auction in southeast KY. I must admit I'm a total novice in phonographs! Anyway, the device comes on and looks like everything works except the speakers. I've tried and failed to find anything on the internet concerning this model. Can anyone help be identify exactly what I've got and what might be the problem?

There may be missing jumper plugs on the rear of the console.
These are usually marked "for Total Sound extension speakers"
They are "D" shaped plugs with three pins - one at the top of the D, one in the center, and one at the bottom of the D.

If the plugs are missing, the two opposite plug connections can be connected together.
Ignore the center pin connection.

Other than that, I can't tell without looking at the unit, or having it on my workbench at the shop.

Thanks Matt, I've confirmed that the jumper plugs are there and both are plugged in.

For something made 40+ years ago and most likely never serviced, it's due.
Deterioration of the components in the amp are normal, and also cause a hazardous situation.
(avoid plugging it in until then)

As well, 40+ year old dried-up grease/oil in the changer will cause issues too.

Every set like that I get in the shop needs a complete "make-over" without a doubt, to perform reliably.
