Tonearm pivot lube

If I understand correctly the pivots must have zero clearance to transmit vibrations effectively. By giving a slight pre-load to the pivot points and would be making sure that the arm stays tight even when the temperature changes. I may be splitting hairs but isn't the abiltity for the pivots to have zero play and very little friction the main difference between a cheap arm and a very expensive one?

The Bio-tracer arm uses the standard pivots but also has an electromagnetic sensing-drive system to keep the needle centred in the groove. It's like an on-demand dynamic tracking force and anti-skating compensation. Thanks for the input

Dear 80Stech: +++++ " There does not appear to be lube on the pivots but I think I might try a very small amount of " +++++

why do you want to do it?. I don't know all the tonearms out there ( vintage or today ones ) but I know several and in no one I find/found nothing like you ask on the pivot bearing ( oil damping is other subject ) and I assume yours does not needs. My advise is that you leave it in " peace " about before you can/could infringe some kind of damage to the tonearm, things are that IMHO the pivot/bearing is the more delicate part on a tonearm.

Btw, do yu read something about or some one told you about?

Regards and enjoy the music.

80stech,

Check out this link. Look at the far right column and you'll find a couple of linear arms in the list, the PS-FL77 and PS-x800. The links show service manuals for both, but I am not registered with Vinyl Engine so I can download them. Anyway, this may just be the information you're looking for on that arm.

Thanks Dan_ed, I downloaded the Psx-800 manual but it doesn't mention anything about lubricating or adjusting the tone-arm pivots either. They are probably assuming that anyone getting that involved would know what to do.

I still would like to know exactly what makes a tone arm "good". Maybe I should start a new thread?
