Realistic LAB-500 turntable at 33 1/3 jumps to 45 rpm

I have a Realistic LAB-500 direct drive turntable from Radio Shack purchased in 1979 that now when I play vinyl at 33 1/3, at random, the platter jumps to 45 rpm.  I am looking to find out who can repair it, has parts etc or how I can go about doing this myself if possible - thank you!

possibly your capstan needs cleaning? remove the platter and locate the capstan which is usually made of brass? if it is dirty, ie; black use cotton balls and neat alcohol (spirits ) to clean it. also, consider changing the belt as it may have stretched?

    I have one that did the same thing. Turned out to be dirty contacts in the speed switch. A little contact cleaner works wonders.

You need to prise that black 45 adapter off. The turntable matt should also peel off.

What's the correct way to use the strobe light to set turntable speed?


The turntable may have a pattern on the edge of the turntable. If not you need a turntable strobe disk that you place on the turntable like a record. The pattern on the disk or on the edge of the turntable will be marked for 50 Hz or 60 Hz frequency.
The strobe marks on the disk or on the turntable are for 33 RPM and 45 RPM and for both 50 & 60 Hz mains frequency.
To adjust the turntable for the correct RPM, turn on the strobe light and the turntable set it to 33 RPM and shine the strobe light on these marks and adjust the speed setting until the 33 RPM marks appear steady and not moving. You may want to check it for 45 RPM as well.
Make sure you use the correct mains frequency marks ie. the 50 or 60 Hz that your electricity system uses.

PL-L50 Pioneer direct drive turntable playing records as if it had a bad belt speed variations in playback, but direct drive has no belts of course. What could be making my records playback speed...


If there is a speed adjustment for 45 and 33 rpm records the contacts or pots need to be sprayed with some electronic cleaner to remove any dust. This is done by removing the bottom of the player and finding the control knobs inside. Electronic cleaner can be found at Radio Shack for around $10 for a large can. It does not take much. Just spay inside the control knobs inside the unit. You will find a small hole where you can put the spray tube that comes with the cleaner. Work the "pots" or knobs back and forth several times to loosen any residue inside the knob casing. Be careful not to shock yourself by removing the bottom. If you are not use to working on electronics it may be better to let someone else with more knowledge tackle the job.

My turntable speed is too slow. I have the optimus lab 1000 and there are speed adjustments on the bottom side of the unit but turning these either for 45 or 33 rpm did not change results. I have already...


Look under the platter or on the bottom of the turntable. There should be two adjustment holes for 45 and 33. You will need a small screwdriver for adjusting these. If this does not work clean the control pots with spray cleaner.

What is required to convert 78rpm records to mp3 format?


The cartridge must have a stylus for 78rpm records. If the turntable does not have a 78 speed play it back at 45rpm. Record it and using the software you have or get one such as Audio Cleaning Lab, just select the option to convert from 45 to 78. You can then carry out any audio modifications to clean it up, then save it as an MP3.
Never use a 45/33 stylus to play a 78 and never use a 78 to play a 45/33 record.

LP audio recording seems to be at the wrong speed


1- The turntable is set to 45 rpm and the album is recorded at 33 rpm. Press the 33 rpm button the red light should come on turn the and be fine.

or

2- This turn table has a fast record mode where you can record a 33 rpm LP faster by spinning it at 45 rpm. If you are trying to use this mode you will have to make a software setting to tell the TTUSB10 digital converter program what mode you want to run.
