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.

About that rubbing sound. Could it be the hoogy that directs the belt from 33 to 45. Sometimes it is out of alignment and only needs to be adjusted with a set screw. Hope this solves your problem.

I own 2 of these things. I doubt - with all due respect - that the rubbing sound you hear is either the bearing or the spindle but almost certainly the brake. There is a simple adjustment to be made. Download the manual from vinylengine and I think it is one of the first things mentioned.

You can even adjust it so that the brake is never in contact with the platter. If you are not using this for radio, I doubt you will need the brake.

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,

Put a small washer under the each of the 3 mounting holes, where the assembly meets the plinth. That will raise it just enough to keep the platter from scraping on the plastic shroud.
