Tonite I had a look at the no-name cartridge in my $10 Technics turntable and held a small drill bit near it and couldn't feel a thing. A 1.5 thou feeler gauge only barely responded so there was a very weak external field with this cartridge. So it must vary from one type to the next. Or perhaps the magnets in mine have simply fizzed out.

AuroraB and all,
concerning belt stickyness, well, i modified my point of view. My old trusty TT undergoes a modification, it gets a new plinth able to carry two linear tonearms or 12"ers if desired. And on this occasion i moved the motor (which is a maxon DC motor from now) from platter edge proximitiy to the utmost outer corner of the plinth. The old motor, a Pabst GS3809, consumed too much space for such.
So the motor changes from AC synchonous to DC ascynchronous with practically zero torque ripple and i do not need the pulley's speed variations to drown in belt slip anymore. The belt will be a magnetic tape (and slippery as such) but the angle of the belt wrapping around the pulley is much bigger. Belt slip will be history, i presume.

Dice,
Any news on this tape-belt ?
If you had slip for a while (metal-polyester) wouldn't it burn?
Have you tried non-waxed dental floss yet? No kidding,all the Japanese audiophiles have a healthy set of biters,you know.
I guess you also require a decent tape-splicing device to work with?

This is a great site! I've been enjoying DIY for close to 50 years, and a lot of my gear is DIY.
I checked machine shops every so often to gather as much stainless steel as I thought might help. Then I was lucky enough to find an electron microscope platform to use as the plinth. Next I found a Teres rim drive. Lastly I found a some some pieces to use as a possible platter. From there and with a machine shop close by, it was really easy! Over those 50 years , I have had a lot of turntables but nothing even close to this!
