Pioneer PL-X100 turntable need help
Hi,
I got to longing for some of my old LPs, especially those that were never reissued on CDs. I dug out my old Pioneer PL-X100 linear turntable. It's been sitting on a shelf in the garage for 10 years or more. I've got a battery operated pre-amp that seems to work pretty well. It works, except... The mechanism that moves the pickup across the LP seemed slow and balky, and eventually got stuck. It looks like the lubricant got thick and sticky. I don't know what it is. Silicone, maybe. It looks like some of it dripped off the mechanical parts and oozed onto the the underside of the lid. I reached inside as best I could and tried to clean up the mess with WD-40. It seemed to dissolve the old sticky stuff, but the mechanism is still slow and gets stuck at times. It appears that the drive motor and belt or cable are okay. Seems like the sticky stuff is the problem. There's probably more sticky stuff in places I can't reach. I'd disassemble the turntable to clean it up more, but it looks like the upper part doesn't come apart. It looks like the dust cover is connected to rest of the the lid with plastic rivets. The dust cover prevents access to the sticky mechanism. I'm thinking about drilling out the rivets in an attempt to get inside. Suggestions? Thanks in advance, Tim |

--snip-- That's one way, but I bet there's another, less destructive one. Turntables are usually shipped without the covers attached. The store or whomever put it together likely didn't use rivets to do so. Good advice about the silicone. But how do I prevent the silicone from getting all thick and sticky in the future? More silicone, every once in a while? Remember, this is a linear turntable. The mechanism that moves the pickup across the disk is integrated into the dust cover, and the whole thing has a very low profile. I suspect it shipped from the factory all in one piece. If a subscriber owns one of these, lemme know if you can see a way to get at that mechanism, whatever it's called. I suspect it would be possible to put it back together if I drilled out the plastic rivets, but that's just an educated guess. The belt is a good idea. Cheers, Tim |

Doubtless.... PLX-1000? I remember seeing a warehouse full of those in 1979, all called backed because Pioneer bought Harmon Kardon and HK already had a linear-tracking tonearm turntable. I wound up getting a PL-600 (not to be confused with the much-later PL-600 which was something much less). Or maybe that was the PLL-1000 -- more than just PL I know that. The PL-600 still works as well today as it did 27 years ago -- with zero maintenance (direct drive, with a 3lb platter). http://40th.com/gfx/audio_hw/pioneer_pl600_1979.html has a pic. I use it nowadays for copying LPs to wave, using an X-Fi Elite Pro (it's got an RIAA MM phono preamp in the external box), and before that a Denon PMA-880R -- hard to find MM/MC pre-amps anymore (the Denon has both). -- 40th Floor - Software @ http://40th.com/ iPlay : the ultimate audio player for mobiles mp3,mp4,m4a,aac,ogg,wma,flac,wav, play+record parametric eq, xfeed, reverb; all on a mobile |

Make that, Pioneer bought Phase Linear,
and so recalled the PL-L1000. HK bought Rabat (their linear-tracking turntable), or something like that, which was that funky gear/wheel/tonearm thing. moi [Thu, 05 Oct 2006 04:31:51 GMT]: PLX-1000?

FWIW, the label on the front panel says, exactly, PL-X100 Sorry, I saw "1000" in there - one too many zeroes. -- 40th Floor - Software @ http://40th.com/ iPlay : the ultimate audio player for mobiles mp3,mp4,m4a,aac,ogg,wma,flac,wav, play+record parametric eq, xfeed, reverb; all on a mobile |

A cheap pop-rivet tool can be had for a few bucks at most hardware stores, along with a modest supply of rivets. jak Excellent suggestion, jak. I should'a thought of that. As fate would have it, I managed to fix it another way. I found a lubrication hole, suitable for the long skinny straw you can put in a spray can nozzle. I tried WD-40 in there, but it did no good. Then I tried a can of silicone lube, in the hole and every other place I could reach. Still no benefit... But after sitting overnight, it was working perfectly. Maybe the new silicone lube dissolved the sticky old silicone, or maybe it was the combination of silicone and WD-40. I'll hope for the best, and I think I'd better burn my best beloved old LPs onto CDs while the thing continues to work. Cheers, Tim |
