I still have an SL-10. I haven't played it in awhile. I might have to fire it up. It benefitted from being placed on a Townshend seismic sink. It is currently fitted with an Ortofon OM20 cartridge. I have the original MC cartridge which I never used very much. I would guess the suspension isn't all that great after sitting in a box for 25 years. Records with a bit of warp at the outer edge always presented a problem due to the clamshell design whereby they would rub and alter the speed stability. The same record would play fine on a conventional table. I would love to use it in my secondary system but space is non existent.
