This is the power supply and motor drive panel from a Pink Triangle Turntable, a very expensive and well respected piece of Hi-Fi...why then use a circuit that looks like it's been built in a school science lab! All the small electrolytic caps were open circuit, most of the large ones were way off value, I changed the six high wattage resistors because they had had a very hard life, the print on the back of the panel breaks if you breath on it, it's that pathetic, all that work done and the motor spins now but not as it should, it has very low torque and seems unsure of which direction it should turn, there are more faulty components that need to found and replaced but now wondering if the motor is also toast!
A DC motor conversion is available but at ÂŁ400 it seems a little OTT. I'll keep going to try and keep it all original.
Oh yeah...as usual no circuit diagram is supplied by the manufacturer!
