Final tweak to the board is the removal of the original 10k pot and 22k resistor and replacement with a 50k multiturn trimmer.
The motor is glued (temporary?) on the original plate as the original synchronous motor came off easily and the plate cut to fit the magnetic sensor.
The pulley is slightly taller so the mount is set as low as possible.
The original worn belt was too long so bought a new 424 long 0.7mm thick belt which turned out to be marginal so had to go looking for something shorter,found a 408 long 0.6mm thick belt at Thakker,works perfectly
Can vouch that the platter runs slower with the thinner belt
,easy to get the speed back up again though
