A bit of a PITA, as you have to work by trial and to remove and refit the platter every time, but once it's right, it remains so for good.
Do not forget to set the pitch control knob in the middle of the scale before you start.
Be careful not to scratch the surface of the pulley with your screwdriver.
Hope it's clear enough.
Thanx Hugues! That worked perfectly for me
. A slight movement up of the pulley made it spin a lot faster. It was easier than I thought. And you are right, I had to do a bit of trial and error, but now it should be more accurate for good. Thanx!
Now I opened my Dual again I thought I'd have a look at the motor, because I think it might need some lubrication. I took the motor out, but didn't manage to take the two motor halves apart. It seems quite stuck. Maybe I'll try to get a snap ring tool to put more pressure between the two halves.
Anyways, the pitch control problem is solved. I'm very pleased
thanx for your help.
