You are gonnaneed to "splain yourself better"--When you say it "selects the B sides--" whadda you mean ?
As for the needle sliding across the record--is the needle good ? Ron Rich

it wont play the 200 sides or even pick them up, it just passes over the tab, it wont trigger the coil eith to flip the switches on the number wheel,

Sorry--I can not make any sense of what you are attempting to say--I suggest that you read the Service Manual, and then re-try to explain what the problem is, using terms in the manual. If you do not have a manual, see the "announcements" section ablove--"where to buy---" Ron Rich

sorry, will try again. on the read out side of the selection wheel the upper selections or the 100's play fine, but the lower selections or the 200's the arm just passes and doesn't stop, i've cleaned the homing wipers as well as the contacts on the selection wheel, but no luck. any ideas?

Start with the hammer coil--burnt ?-dis-connected ? Contact on "ring" making ?--follow it back to the "side switch" contacts--that's the only difference in the circuit-- Ron Rich

I don't have the schemo to look at, therefore I don't know the exact terminology used by RO--but I would call it the "A-B side switch" --follow the schemo--it should tell you-- Ron Rich

Hey Ron, that would be the "A-B Snap Switch" you're thinking of.
