How do I ground this cartridge when there are only two connections on it. I hear hum when the turntable is connected to my Midwest 162r radio. Any suggestions would helpful.

I didn't mention an important thing, the record player is not original to the Midwest. It is a Philco model from 1959.

How about some photos of the record changer ?
Underside phono connections and tonearm/cart
connections. Top of changer with platter removed.

Photos, lousy focus took them with my kindle.

Does the hun go away when you short the two cartridge leads?

How do i short the leads? I restore radios i know nothing about phono cartridge wiring.

1. With the amp powered up, just touch the 2 leads together.

2. From the photos, it appears that the audio leads are
surrounded by meshed wire ( shielded ).
And that there is a clip soldered onto the mesh wire.
Is this the case ?

3. Have you cleaned the Sonotone connection blades and
the inside of the clips on the cartridge wires ?

What kind of wire are you using to connect the phono? To me it looks like zip cord. Or lamp cord. If so, then that's the problem. You need to use shielded cable. It has a center conductor with a wire mesh around the outside that shields it from hum. You can use an old RCA to RCA patchcord and just cut off one end. Just make sure it's shielded cable.

You are right sir i am using a cable that i had lying around. Tomorrow i will put in a good shielded cable and try it out. I will report back to all with success or failure.

Make sure the ground lead connects to the metal changer chassis as well as the cartridge lead.
