I have bought a 4000 on e-bay in working order!However it got damaged in transit(I was warned)The problem is the cartridge holder/connections on the arm.I am trying to repair myself with a very good service manual.The arm (Part 2850052) is a push on fit to the arm holder.This arm was later modified but requires a replacement counterbalance weight.So its the earlier arm I require.Can anyboby help! I also need bulb OIL 1 (Photo resistor light 6V 30mA) and belts,although I think I can source these.
