"New" Thorens 124 sounds great, but...


I have a "new" (completely refurbished by STS classic turntables). I know that there is a very heavy lower platter, and it looks like it is made of iron. There is a top platter that seems like it is made of aluminum. On top of that, I have a turntable mat that is made from carbon fiber and cork. I use a Funk Firm FX-R tonearm, and a Benz Ruby Z low output moving coil cartridge.

My tonearm is acting weird. When I lift up the cueing mechanism at the end of the record, it wants to quickly run back to the armrest. Scary fast - as if the table wasn't level, or the armboard wasn't level. But both are perfectly level. I took this tonearm and cartridge combo off of my Linn LP 12, where it acted perfectly normal. Again, it sounds great - no break up on any channel. And the down force is consistent at all points of the record.

Is there any chance that there is a magnetic force at play here? No amount of playing with the anti skate seems to matter. Curious what you folks who have this table, or others like it may think.

Early 124s had a ferrous platter. MCs became popular later, and that platter created havoc, just as you describe. So they made a new platter, non-magnetic. Swinging to the outside is repulsion, and playing with adjustments won't change the laws of magnetism. It may affect VTF too, so check it when the stylus is on the platter, then higher, and see if they differ: if so, compensate. But how does it sound when playing? If it plays and sounds as good as you hoped, then ignore the idiosyncrasies. It's a great TT.
