My old '76 Sansui manual reads "Every 3 months or 200 hundred hours of play - lube the platter shaft & motor with a few drops..." Is this excessive, not enough.... I think the last time this table was oiled was 2 years ago, and it still works great.

Surely the manufacturer knows, and I would follow their advice. A new car will "work great" if you don't change oil for two years also, but it isn't something I would admit to doing in public. Nor will it do the car any good. Why not follow the manufacturer's advice. Sort of reminds me of an old Mark Twain quote! I constantly use my table and probably oil it 3 to 5 times a year on the shaft, probably 3 times a year on the motor. I always notice an audible improvement when the shaft is re oiled. It not only prevents bearing wear and resulting noise, it also serves as an "isolation barrier" of sorts between the subchassis/bearing, and the platter/shaft interface.

Looking at my AR manual, and AR manuals from other models on the vinyl nirvana site, 1 year is recommended for them. I guess I'm a little over zealous, but no harm is caused by too frequently changing lubrication, contra not often enough! A quiet background requires a high quality bearing, and any wear or slop transfers directly to the platter, which transfers directly to the cartridge stylus. Your tables manufacturer recommendation was given for a reason, and while it does sound excessive, I'm certain that they recommend that for a reason, why doubt them. There is an "exclusively sansui" site forum on audio karma site perhaps someone there knows why they recommend such frequent oilings. I would otherwise default to the manufacturers recommendations over my or anyone's guess. After all, they did design it. Also, this is a 70's table and lord knows what gunk and build up are in the well. Clean it out ( lint free electonics Q tips) and refill, then follow sansui's advice. leaving it otherwise will raise your noise floor at best, as well as increasing wow and rumble. At worst, it would further damage the bearing. Regards,
Russellc
