I received a sheet of mu-metal magnetic shield today and installed it in my TT-101. Here is the Before image showing the interior damped with automobile damping sheets. Here is the After image showing the mu-metal sheet cut into shape and placed...

I can't vouch for the app but the phone has a compass in it which has to be a magnetism detector. So if the app tells me that there is a concentration of magnetic field in certain places and if it is consistent in that reading across multiple test...

I am using "Teslameter 11th" from skypaw on an iPhone. Gary

The app measures micro tesla or mili gauss - both seem to be measures of magnetic fields. If I said that I know much more than that I would be lying. I don't yet know if I will cover the motor area - leaving ventilation space or make the mu metal ...

Is no one interested in the magnetic fields concentrated at the normal arc of the cartridge? It would be helpful and interesting if someone with a smartphone would install the Tesla app and repeat my experiment. Is this a problem? Does it effect a...

OK, now I am confused and a bit concerned. I used the Tesla meter to measure stray magnetic fields (as the device tells me) and lo and behold the only area that had high readings was at the top of the platter mostly on the right side of the table....

Lewm, I think the belts are a good idea but insufficient. You need the suspenders as well on those pants. By that I mean the sound dampening sheets. On my iPhone I have an app called a Tesla meter which measures stray electrical currents (RFI). I ...

Lewm, the fluid was brown and had particulates in it. The bearing looked fine, the plate is soft white plastic so was dented by the bearing but otherwise fine. I do not recommend opening the bearing up unless you have detected a problem. I thought...

Halcro, I am happy for any (if any) role I played in inspiring your creativity. In our crazy hobby, everything matters and often it is impossible to figure out what does what to our precious sound.Audpulse, Sorry but no pics available on this one....

Which part interests you - the leveling or the thrust plate adjustment?

I haven't been on this site for a while and just caught up with Halcro's brave changes. I admire your "out of the box" thinking, Halcro. I could never feel comfortable looking at the electronic guts hanging out of my TT.My TT-101 is now seated on ... 
Who needs a MM cartridge type when we have MC?
Lew, I am very happy with a combo of a lead Merrill mat (just a thin sheet of lead - maybe a pound) covered by a thick Achromat. I have both of these spray-glued together and then removable double-stick taped to the platter. Hitting stop doesn't b... 
Who needs a MM cartridge type when we have MC?
Lew,my QL-10's plate says "120 volts, 60 hz, 23 watts". No choices offered. Mine does not have any selector switches, I would be surprised if yours does. But, perhaps yours is a later batch with a more sophisticated ac to dc power converter. Mine ... 
Who needs a MM cartridge type when we have MC?
Lew, Sorry, I thought that you knew that I do have one for a few years now. If you look through the various threads where these have been discussed you will find that I have done a lot with mine. Yes, your suspicion of leaky caps may well be spot ... 
Who needs a MM cartridge type when we have MC?
Lew, when you first power-up the TT-101 let it warm up for 5 or 10 minutes before hitting speed selection. It would also be good to spin the platter in both directions to loosen up the bearing and wake up the speed sensor. If it starts to spin to ...
