Technics SL-10 Linear Tracking

If you can't find an AC power cord to fit then you can go with the DC power supply. As for the MM/MC switch, you will still need to use a phono pre amp. The switch only boost the gain from MM level to MC level. If you are using the original MC cartridge that came with the TT, and only have an MM level pre amp you can set your TT to MC and it should work fine. If the cartridge has been replaced with an MM version, then leave it set to MM.
After being in storage for a while you may experiance some problems with the arm wanting to stop in the middle of a track and go back to home position. Clean the track and apply a little sweing machine oil, that should help.

You should walk over to Goodwill and buy a better turntable. Should be less than the cost of the manual for that groove chewer.

I don't know if Viridian speaks from experience or just his own opinion. I speak from experience and like the turntable. I have done a direct comparison in my system against a Project Wood Classic fitted with a Sumiko Blue Point. I am currently using an Ortofon TM20 and previously used Shure V15. The Project table certainly wasn't any better and way less convenient to use. I have LP's which have been played for over twenty years and still sound fine. No chewed grooves here. If you can find a power cord and get it running it will provide performance equal to the budget Project and Music Hall offerings.

Yes, experience, though I did not own the SL-10, it was a friends, and yes, it did recut several records. He asked me to come over and have a look at it. My impression was that the carrige did not have tight enough tolerances to keep the arm tangent and that there was also the potential for high horizontal friction. Those are just impressions though and I have no scientific data to substantiate them. I can tell you that the table was causing excessive wear in the records that it played. Again, it may have been defective. Generally, highly complex machinery that isn't too expensive can be trouble. One sample may work, and another may not. I suggest basic, direct drive tables with pivoting arms with universal headshells because they have but two moving parts, the platter and the arm. They tend to be quite immune from common problems of ageing. I can make no comments on sound quality as I did not have the opportunity to use the table in a known system.

I have a Technics SL-10 Linear Tracking Direct Drive Turntable that needs a new cartridge and needle. The original # was 310-MC.

Does anyone know what kind might fit or replace it? And where I might get one?

Thanks
