Luxman PD-288 Help

Post by Timmyjones » 12 Feb 2019 13:48

Hi!
I am new here on vinylengine, and thought maybe I could reach out to all the educated members here to Help out with my turntable rescue. I was visiting a HiFi store where I have worked in the past (for over 20 yrs), and there I noticed this Luxman PD-288 in a pile destined to be thrashed. My old boss said I was welcome to it, and I thought why not.
It was in quite a state.

Now, I am not a young man anymore, and My Hi-Fi interest has been dwindling. I blame the kids and my 100year old house. I didn't even have a good system to hook this up with anymore. But I was itching to see if I could fix this turntable. Pretty soon it was all I could think of, and my Hi-Fi interest were suddenly right where I left it. I started peeling off the rosewood vinyl covering with the Help of a heating gun. The vinyl was damaged and not looking pretty. My plan was originally to paint the thing black, but underneath the vinyl I found that the plywood was finished with a nicely jointed wood veneer. Go figure. I think it's oak or beech or something. So I sanded it down, and waxed it. The power cable and interconnect cables were completely stiff, so I decided to add input/outputs instead. There were also a couple of issues with the arm that I had to fix. Here is the result:

At this point, I got to admit, I was rather impressed with myself considering I never been a vinyl man. My days working at the Hi-Fi store, were the glory days of CD's.

I would like to add a few tips for others repairing a similar Luxman turntable. If you have to replace the antiskating thread, it should measure 120mm. If you need to replace the automatic function belt, it should be square, and about 2x2mm. The measured total length for this belts operation is 130mm, subtracting 10% you should end up with a rubber belt measuring about 117mm. This part can be found at gbaudioshop.co.uk or turntableneedles.com. In the service manual this belt has the luxman part number UZQ0003, and is also used for PD-289 and PD-375.

Well, this was fun, but I am afraid this is where the happy story ends. I bought myself a new amplifier, and hooked everything up. The platter spins, but when I hit the start/cut button nothing happens. The arm just sits in the armrest laughing its counterweight off at me. Obviously, there is something wrong with the auto-mechanism, but I have been staring at it for a long time now trying to figure out how it's supposed to work and, -nothing. I am completely blank, and not that impressed with myself anymore.

So, is there perhaps any chance anyone here on vinylengine could Help me with some pointers? It would be greatly appreciated.

Br, Thomas.

Old solid grease it the usual suspect. Strip down, clean and re-grease. Its Auto only right?

Yes, auto only. I was afraid I would have to take the mechanism apart. Lets hope I am able to put it back together again. Should I lubricate the automechanism motor as well? If so, could I just use some sewing machine oil? I have read you should probably use white lithium grease, but I’ve only got a CRC multipurpose EP Lithium grease. Will this do?

Thanks mate

The grease part of my question was for the plastic gears.

Toaster999: yeah maybe I should check that the motor works first.


Agrippa: Thanks! I was hoping someone would say that;)

Well, after looking through the service manual I was able to get the arm moving. Trouble is that it lowers 15-20mm too soon. According to the service manual found here on VE for pd-288/289 the lead-in adjustment is done by turning an eccentric pin. I tried this, but no luck. I suspect this only does fine adjustments. Any Help would be greatly appreciated.
