Pioneer PL 200

I've had a Pioneer PL 200 for years and haven't used it for a long time. My son is now into LP's so he started using it. however it runs constantly, it doesn't turn off when the arm is placed in the cradle. I'd like to open it, inspect the inside and maybe spray some cleaner in there. I don't have the manual so I don't know how to open it. Can you guys help me open it and also provide suggestion for correcting the constant power on state. Thanks for any help I can get.

Technically, yes. For the sake of the electronics, we are looking for a 5k potentiometer. Fit is important though. Also, you'll want a pot that has a good range of travel to it (300 degrees of rotation), for the fine-tuning.

One might be able to find a potentiometer with a longer shaft, and that can always be trimmed to length with a small hacksaw and then filed a bit with a small mill file. If you can find one that will keep you from having to solder on some lead extensions that would be great.

If you really need to order the part from www.mouser.com, then contact them and ask if they'll ship overseas, but chances are that local dealers will have the same part if you give them the Mouser part number [313-1230F-5K] as a reference.

If the soldering is a bit much for you, just have a local electronics place handle it for you. It just depends on how badly one wants to restore the old turntable to the performance it had during its glory days.

Good luck!

By the way, for those that need to replace the isolation rubbers on this turntable... consider checking out a 1/2 diameter copper tube insulation foam. It's available at Home Depot or Lowes. While it won't provide a pretty solution, it can be cut into 1/4" thick slices and threaded onto the springs. It'll provide some shock resistance and make up for the space that the insulation rubber previously took up.

The insulation rubbers on my turntable fell apart when I took the feet off. They had completely deteriorated. Unfortunately with such aged equipment it becomes necessary to become good at finding substitutions.

By the way, I installed the new potentiometer. While it wasn't a perfect fit, it worked out super (mechanism-wise). I needed to solder on a few 1/4" copper leads to make up for the shorter leads on this new pot.

Good luck!

By the way, for those that would like to replace the potentiometer which functions as a speed control. I believe I have tracked down a suitable replacement part.

Check out: www.mouser.com. Part number: 313-1230F-5K

I was so annoyed with the scratchy pot that I finally had to replace it. This problem went on for years but finally got to the point where the records were speeding up and slowing down without much control. The scratchy pot is the culprit.

One will need to do a bit of disassembly and de-soldering, first though. If you don't have the tools/skills then perhaps it's best to leave it to a professional.

Good luck.

I just opened up my PL-200 this weekend. The speed adjustment potentiometer needs replacing, most likely due to carbon deposits. Unplug the unit and place it on a table. Remove the cover of the unit, the plate, cartridge, and anything you can, first.

You can open the unit up if you unscrew each of the "feet", pads, and remove them. Place the unit on some thick pads or towels to cushion it, so that the underside of the unit is facing up. Once you remove the 4 screws you should be able to free the backing from the front cover. You won't be able to get too far without disconnecting some of the cables inside. Once you have detached them, it'll be best to turn the unit around and work the front cover off at an angle, to clear the arm.

I doubt that cleaner will remedy your problem, though. It's sounding more like the control or possibly a physical wire/device that sets when the arm is no longer over the disc area.

Perhaps someone else can assist with specifics relating to your particular problem.

Good luck.

Pioneer CDJ-200 CD player will not read discs?


You need to be a bit more specific. It might be a formatting issue, in which case, you need to convert your music that's on your cds. The songs must be in "CBR or Constant Bit Rate" format. Most songs come in Variable Bit Rate format, which the 200's aren't able to play. Get a music converting application, I've used dbPoweramp's converter for quite some time, had to buy an MP3 license, but it was worth it. Unlimited conversions = more fun with the tables :) good luck!
