Question about Audio Players & Recorders
1951 model Webcor 1133-1 monaural phonograph.
Most of these very old turntables used an electric motor which turned a rubber wheel that pressed on the rim inside the platter. No spinning would indicate that either the motor has stopped or the rubber wheel is not touching.
As far as service manuals go I doubt you will find anything on line. Your best bet is to go to a main library in some big city that has a section dealing with technology or mechanical engineering. They might have servicing books for Radio and TV engineers for the 1950's which cover the model.

you will need a little box called a pre-amp. This hooks up between the turntable and newer receivers without a phono input. A basic explaination & drawing of this type of setup can be found here

if it arrived by mail then the sender might have screwed the transit screws down to avoid damaging the phono , i am not familiar with memorex but if like most turntables there should be some big screw heads visible on the top of the phono or possibly even under the platter all you have to do is unwind the screws until the platter unit moves freely [you should be able to push it up and down a little bit ]

Probably a bad relay switch. Open up the turntable. Identify the motor that spins the table. Follow the wires of that motor to, perhaps, some type of little circuit board with a relay. I have a Backley-Cardy 322-487 classroom phonograph which uses a Califone 1620 amp and a BSR turntable. To get the table to spin, you have to move the tone arm. Mine doesn't move and I'm in the process of replacing the faulty relay that is the problem.

SOURCE: I just bought a Memorex
I know this question is old but I work on these specific units and have come across this same problem. What I have found out is there is a capacitor on the turntable motor that is there to reduce any noise that is caused by the motor itself. What I have done is wiggle the capacitor to see if the solder connections are intact. If the connection is loose the capacitor will not filter the noise and the noise is picked up in the CD burner and then recorded on the CD.
To get at the insides of the turntable you need to remove ALL the screws on the bottom of the unit then flip it back over. You will see a split where the front of the unit is attached to the base. Stick a flat headed screwdriver into the slot and twist gently to pop it apart. Then work your way all the way across the top of the front doing the same thing. Once it is free tip up the top half of the turntable to the left and prop it up. The capacitor is on the part you flipped up near the center of the turntable body attached to the motor that drives the turntable. It is a 104k capacitor. There is one on the tape deck motor as well.
