It's actually a different motor in yours, but the supply still goes to the red via the resistor, and the cap still appears to be between red and blue, and the same value, although a different type. Based on that, I think I'm going to start with 15k now, and see if the motor runs, and if it does, if it has enough torque to drive the platter. Thanks very much for taking the trouble to post me the piccy. Appreciated. Arfa

Appreciated. > > Arfa > > Hi Arfa Further info. The data I supplied earlier was from the Planar 3 upgrade motor assembly. I have just pulled out the old motor and PCB. It has only 2 components on it. 1 x 220nf 250v ac X rated cap manufactured by Rifa. 1 x 12k 2-3 watt resistor, 8.5mm dia x 25mm long. The resistor is a mid brown body colour and the bands are quite hard to read but measurement confirms 12k 5% (as in brown red orange gold) The brown and orange are hard to differentiate The motor is a Philips 110v 50hz 250 rpm (12NC 990411131613) date of manufacture 1985 with the same colour leads I would suggest going with what you have in the 12 - 15k ~ 5 watt resistor. Check that the voltage to the motor is in the region of 110v under load and it should be good to go Cheers DaveD

I just had a look, and I haven't got a high power 12 or 15k in stock, but I have got some 47k 2 watt film resistors, so to save time and get the item back to the customer (he's already put up with me being away on holiday for 2 weeks !), I'm going to put three of those in parallel as there's plenty of room. Thanks again, all. Arfa

Would not some 1/2 watt resistors together giving 12K be better?
