Rubbing sound fromTechnics SP 15 platter

I just salvaged two Technics SP 15 decks with AT tonearms from a closed radio station. While both decks spin, each makes a rubbing sound when the platter rotates.

I have not investigated yet, having no real experience in turntable repair. Any thoughts what might be the problem? I have no idea whether these tables were recently in use or not,,,my guess is not. I'd rather not spend $$$ having a tech trouble shoot if the problem is as simple as adding oil or as serious as DOA.

I also secured a truly vintage Fairchild belt driven transcription broadcast table (cicra 1960)with 2 original 12" Gray Research arms, cartridges and integral metal stand. The set up must weight close to 100#. I would like to have it restored. This table is a real collector's item. Any thoughts who to contact?

Thanks.

I just got an SP-15 which was also suffering from the rubbing sound, but it seems like it's because the conical sleeve/bore are worn causing the platter to sit too low on the spindle.

The rubbing sound is being caused by the underside of the platter rubbing on the plastic cover that sits over the mechanical brake. Removing this cover stops the rubbing sound.

Cheers,
Paul
