Finally got the Headshell & Cartridge together for the PX-2 except the buttons on the right board don't work, left & right, up & down, cut & play disc size etc. I've sprayed Isopropyl Alcohol on the buttons with the board removed but nothing. I replaced the belt that goes from the motor to belt drive & tone arm moves fine but only when i push it then it moves all the way across i guess because the left board is faulty & it dosen't know what disc size etc or the circuit isn't complete. Have you had similar problems? The mechanical side of the Tonearm is fine, does anyone have a spare board for the 9 buttons on the right? Replace the IC294?
