    Roadstar rs5750 = Gelhard rs5750 (1978-1980)

    Hey everyone, I wanted to share some bench notes on a Roadstar RS-5750 I recently finished restoring. While the Roadstar name doesn't usually command much respect in audiophile circles, this 1978 model is a legitimate "sleeper" with some serious engineering under the hood—and a few odd budget...

    Telefunken TS 860 vs. Sony PS-212 SH.

    Hey everyone, I'm looking for some opinions and advice regarding a potential turntable change. Currently, I own a Telefunken TS 860. It's fully functional and complete, and I've personally serviced it (cleaned, lubricated, etc.), so it's in great shape. I've come across a Sony PS-212 SH that's...

    Technics Turntables: Diamonds in the Rough?

    After owning and loving my mid 80's AR EB101 for over 30 years, I'm finding myself intrigued by the Technics direct drive turntables from the 70's and 80's. Unfortunately, I'm not in a position to buy even a used SL 12 or 1500 as they appear to be going for four figures in working condition...

    Sansui P-D31 (direct drive, servo) plays slow, any way to fix?

    I scored a Sansui P-D31 turntable at Goodwill for 12 bucks. It’s definitely a weird one! All of the controls work beautifully, spins great, consistent speed… however, the speed for both 33 and 45 is consistently slow, by about a second each. I read through the manual and there doesn’t appear to...

    Realistic Lab-8500 a.k.a. Canadian/Euro ltd Lab-500 - Feedback, Thoughts, Reviews?

    Looking at picking up a Lab-8500 TT. Does not appear to be much info out there on them. As far as I can tell it was a Canada (and possibly Euro) custom edition of the Lab-500. Research points to it being built by Mitsubishi (possibly ITT). It's a quartz lock direct drive. Has a repeat play...

    Yamaha p-520 turnrable not spinning?/how does a direct drive motor even work?

    I have made a post about this before but sadly did not receive any replies. I have a fairly simple direct drive turntable made by yamaha. However it doesn't spin. I replaced the caps and tested all the other parts in the circuit but to no avail. I think it probably has something to do with the...

One other thing I noticed is that the strobe light doesn't turn off if the arm is in the off position but it does start...

    Yamaha YP-D4 Turntable speed issue

    Hi all, I'm having a bit of a problem with a YP-D4 direct drive turntable from Yamaha. Though I set it up like in the service manual the speed wobbles a bit, it is more obvious on the strobe that moves bit left and right. I've also made a speed test with an app, maybe someone could give an...

    Sony ps 212 motor lube? how to lubricate? I ask for help!

    Bought this turntable. I replaced the capacitors, adjusted the tonearm, cleaned the variable resistors. Everything works perfectly. Does the motor spindle need to be lubricated? The motor runs quietly, keeps the speed, but the turntable is 30 years old, maybe the grease has dried up? Thanks in...

    Sony direct drive turntable platter issue

    Hello, I own a second-hand Sony PS 4750 direct drive turntable. Under the platter is located a sensor (looks like a tape head) that sits close to a magnetic coating located under the platter (so it keeps a constant speed). Some of the coating seems to have scratched off, so the turntable...
