Sony ps-x6

[Jelonkielon]

Hello, I’m new here and I recently became the owner of a Sony PS-X6, which I switched to from my old vintage Polish PRL-era Unitra Bernard 461.

I wanted to have it serviced, because initially the speeds were not working properly (33 RPM held speed, 45 RPM did not), the record size selector was not working, and the repeat button was not functioning.

When I heard the cost of professional servicing, it pushed me to start reading forums and looking for answers on my own.

The speed issue is no longer a problem — it was enough to gently clean the black sensor that works with the magnetic strip on the platter using a slightly damp cotton swab.

I also located the problem with the size selector. I’m not sure whether it is cracked or just loose, but I’ll get to it later. If it turns out to be cracked, I plan to use epoxy resin, since the selector is still in one piece.

After slightly moving the entire control panel assembly (start/stop, repeat, and record size selector) — without removing it, just gently wiggling it — the repeat button suddenly started working (magic).
Has anyone experienced a similar issue?
I’ve read that these buttons can be temperamental. Could using Kontakt PR cleaner help? Or is this more likely an issue with old solder joints?

Now, getting to the main reason why I’m here. In the service manual there is no mention of where lubrication should be applied (I have silicone-Teflon grease TF, which is safe for plastics). Could someone please point out the lubrication points for me — red dots for grease, blue dots for oil? I’ve attached photos below.

One more thing that’s been on my mind.
Should the mechanism be audible when the tonearm returns to its resting position?
When the tonearm moves onto the record it’s absolutely silent, but when it returns, the operation of the mechanism can be heard.
It’s not loud, but it makes me wonder whether it can be lubricated to operate more quietly.
If so, which part should be lubricated?


I also couldn’t understand why someone previously applied grease to the springs — does that make any sense?

Best regards, and thank you in advance for any help.

tables of that era used a lubricant which has turned to wax over time. You may have to remove the bottom cover and carefully clean out the old lubricant and replace with fresh white lithium grease or similar. Its been a long time since I worked on one of these. You may be able to clean enough of the old grease without disassembly. Not sure since I have not tried it. IF you disassemble the arm mechanism be sure to take tons of photos or draw a number of sketches so you can figure out how the pieces went back together.

Thank you for the reply. This is exactly how I’m trying to do it—without digging too deeply into the internals. Only what is visible and where I can reach. The only issue is that it would be helpful if someone could precisely point out which components require grease and which require oil. Grease is still easy to identify because it’s yellow, but oil is not so obvious. (I do not intend to disassemble the tonearm; for now it works very smoothly.)
