Spray some WD-40 in the can's cap and use something like a toothpick to drip a few drops inside the volume and tone controls where the three terminals are on them, turning the controls back and forth many times as you do it. Also put one drop where the control shaft enters the threaded bushing on the front of the chassis.

Put one drop on each of the moving contacts of the function switch and turn it back and forth a number of times. Try not to get any (or much) on the insulating wafers of the switch. The switch will also have a mechanical detent that keeps it in each position. That could use cleaning and a little spot of light grease.

This should get rid of the scratchiness of the controls.

If you switch to phono and then touch the center pin of the phono jack you should hear a loud hum from the speaker. If so, you could test with your MP3 player. Unplug the wire to the record player.

You need an RCA plug to go into the phono jack on the chassis, or you could use a patch cord with alligator clips on one end and a plug for your MP3 player on the other and hook up under the chassis. The center lead of the cord goes to the center pin of the jack, and the outer (shield) of the cord goes to chassis.

If the adjustment screws of the IF transformers and the tuning cap have been played with, about the only way to get the radio aligned would be with a signal generator. If you know someone in town with one, good. If not, check back. I gotta 'nuther idea.
