How do I adjust the speed on an old record player?
I have a Columbia 360 record player from the 1950's and it plays records a bit too slowly. The 33 rpm speed needs to be adjusted a bit. Is there an internal adjustment dial or screw that will do this on old record players?
The first answer about lubricating things is good, but it is probably the drive wheel to the platter (that's what most had then). It could probably use a new drive wheel, but that's going to be difficult to find. It is probably slipping, because the rubber is hard or the turntable is corroded.
If it's not corroded, then you might try a very light sanding with very fine sand paper or an emery board to rough up the rubber very slightly. You don't want to take off a lot of the rubber, because then the diameter will be so far off that it will never work. Just enough to unglaze the surface and get something that feels like rubber again.
Also, there is a spring that presses the wheel to the motor drive and the turntable. It's possible that the spring is sprung and needs to be replaced. Again, this will be difficult, because it was originally tuned for just the right amount of pressure to run properly. There may be some adjustment there -- you'll just have to check it out.
I played with some old turntables back in high school and these are some of the things I ran into.
