Yes!
Check the solder joints at the connectors. I had that on my two examples.
Martin can supply the small belt.

Will the platter spin easily by hand?
martin
the platter spins easily by hand. I will double check the solder joints.
Good idea.
Don't forget the CPU socket.
Did you replace ALL caps in the kit, nothing more, nothing less ?
Martin
almost all the caps, the cpu was the hard one as you had to disassemble it and then each end of the cap had to fit into the hole plus have a extra conductor solddered to it. If I made an installation error, it was probably that one.
I did not change the caps that werren't on the circuit board. There is a smaller circuit board on the base of the turntable between the arm mechanism and the platter mechanism. My kit did not include a .47 uf 160 volt cap that is there. The one in there is a Nichikon so it may have been changed by the previous owner?
Next to the spindle mechanism is a small board with two caps. I did not change them as well. Maybe i will see what their value is and then see if the kit has them. I have 3 left over caps in my kit.
... a .47 uf 160 volt cap on the subchassis board ...
Are you sure about these values ?
Normally it's a 47uF 10 or 16V (plus a 1uF 50V).
Worth checking.
Martin
it is defintaley a 160v 0.47 uf rubycon capacitor. It is the only rubycon in the unit so it may have been changed by the previous owner. He dealt with thte B&O shop locally so i doubt if it was an ineperienced tech.
I replaced the two capacitors with the ones in your drawing. No change
i cleaned the tacho disk, no change
When you power up the unit, you get a medium hum for 1/2 sec. The hum comes from the two coil / magnet devices that turn the platter. When you press start, the hum is continually on and it is about twice as looud.
Sorry for asking but you have the black subplatter fitted, right ?
It's an essential part of the eddy-current motor that drives the platter.
Martin
it wasn't but it is now and no differrence.
BTW, now it makes sense how the turntable works.
