Humming on pfl
50hz hum. Turn off most of your home equipment , turn only your table on, if it still hums it\'s your transformer and that\'s too bad for your wallet. And you also don\'t have those led lights which
is a fashion statement at the moment on your table, they are not quite good for causing distortion. And in your home are saving-lights. especially with dimmers and lcd plasma tv\'s a major cause of distortion. But a steady , low freq hum is your transformer and i have a stethoscope, not for that purpose:). Then you don\'t have to search. But they ain\'t cheap, the upgraded in 2009 ones.

It needs to be taken apart. The bottom needs to be removed. Not an easy job if you are not mechanically inclined. There are pots inside that need to be sprayed with contact cleaner. Pots are under the knobs that control the speed. They have holes on the sides of them. You can purchase cleaner at a radio shack or electronic parts store or online.

TECHNICS SL-B280 DUST COVER W/ HINGES
All parts are discontinued for this model. The SL1200MK2 dust cover will not fit this turntable. You can actually have a dust cover made rather simply and cheaply (depending on where you live). Just take the dimensions to a PLEXIGLASS or even a GLASS shop. You can even purchase the Plexiglass yourself, cut it, and glue it together. I would suggest getting it professionally done. You can use any high impact plexiglass. Get something that is resistant to scratches and discoloring.

Pitch is not working correctly
a) "dirty" main power switch, comes from sparking when power switch has been used a lot (happens also with some CD/DVD players - makes them loose some power - consequently, focus and/or spindle will not work properly). Try cleaning it up or replacing it (bypassing it will tell you if the switch is really the problem).
b) bad contact on the speed control slider (try moving it while slightly pressing it downwards, see if there is any change, if there is, have it cleaned up or replaced)
c) a problem with electronic speed control, possibly a loose solder connection or a bad capacitor somewhere in the speed control circuitry. If the circuit has fuses in it check if they are all ok. I once had a problem with a turntable that had a fuse "partially" blown (people were using the turntable a lot for "scratching" which overheated the fuse but hadn't blown it out, yet it changed in resistance from zero ohms to a few hundred ohms - the turntable began to **** and the speed was changing).
d) none of the above, it could be something else that i can't think of right now
hope ya get it workin'
