Fisher MT-6225 platter grinding

Postby Hopewrecker » 18 Mar 2012 15:57

Help please! I've lurked a little and tried searching for answers but thought I would go ahead and ask for help. Hopefully someone here has this turntable or has worked on one before. I got this Fisher mt-6225 for free and it was pretty gunked up from being in storage for a while. I cleaned it up and tried to get it running but the magnetic strip under the platter rubs against the "sensor"(sorry, don't know what they're called)strips as it goes around. It's enough to throw off the speed, make an ugly grinding noise, and I just want to see if there's any way to fix this. Some way of sanding this magnetic strip down a little. I'm also wondering if there is any way to actually adjust the sensor part so it's just a hair farther away. Doesn't look like it, but maybe?
Any help would be greatly appreciated, thanks in advance!

Did you ever get this problem fixed? I have a Fisher MT-6440 with the same problem. I don't even know how to get the platter off to see what's going on underneath. Let me know if you had any success. Thanks.

Do not ever sand down magnetic strips, on any turntable, unless you want an awkward door-stop.
Adjust position of sensor, if necessary.
There is a service manual for the MT-6330 here:http://www.vinylengine.com/library/fisher/mt-6330.shtml

Thanks, Alec. I DEFINITELY wasn't planning on sanding anything down. I just want to be able to remove the platter to see what's going on underneath. I looked at the Owners Manual (I actually still have this one) and Service Manual you referenced but am looking for instructions on how to get the platter off. Any ideas?

I do not know this specific turntable.
Normally, one removes the mat, then lifts the platter off. I have seen turntables that have the platter attached with screws, some held in place with circlips, some with a sliding tongue that engages a lip under the platter, or a screw in the side of the bearing that rode a slot in the spindle, etc. I don't know that Fisher ever used any of these. The manual will have this information.
Often the platter gets stuck to the spindle. In that case, lift the platter, and tap the spindle with the plastic handle of a screwdriver.

Cheers,
Alec

I have an MT 6335, to lift the plate, take it by the holes with your thumb and another finger,and lift and it at the same time with the other hand press the axe, the plate should come up, if it is stuck, spray it, with a litle WD40, then clean everything

Tried this, pulled as hard as I dared, even after a little WD40.

This is very similar to the 6250 and I rebuilt one of these and owned two. I still have the platter off one of these and I can tell you it will come off. No force is needed other the the weight of the table itself when you pull the platter straight up. it may resist but it does come off. Don't spray any lubricants if you don't have to.

I just got a Fisher MT-6225 from my father-in-law and the magnetic strip has corroded off the turntable. Is this something I can fix?
