    Kenwood KD-650 Bearing Question

    I recently bought a Kenwood KD-650 turntable and love it! However, I suspect that the bearing might need work. When I bring the platter up to speed at 33 1/3 rpm and then power it off (bypassing the electronic braking) the platter spins for maybe 10 seconds before coming to a halt. Compare...

    Tonearm bearing cones, black - polishable ?

    Hi, I am about to give another flush to my Empire 990 tonearm bearings. This time I am thinking of also polishing the bearing cones. On this tonearm, unlike the others I have seen, the main steel bar with the cones is black, not shiny as usual. Can I polish this type of steel ?

At record height, the azimuth is fine, but at rest is leans to the left, and sitting on the table it leans to...

    Sony PM-5100 Jammed shaft - Thrust assembly - what to do?

    Hi guys, I'm restoring this Sony PM-5100 turntable which is in excellent condition apart from a jammed thrust bearing. I have no idea how to go about trying to free this up or remove it.

    HW-19 jr platter upgrade

    Hi guys, I spotted a nice lead-filled black acrylic (delrin?) platter with an inverted bearing (no cork on the bottom though, maybe it was just removed?) on evil-bay. I believe it's the MK-IV? But I'm not totally sure. I can weigh it when it arrives. Seller said it's 1" thick. I may have been a...
