Again about 5 hours working and trying at the Zero 100.
But first in steps:
First: My platter has a 50hz decal and i checked: nothing has loose, it's still tighten...
Second: Problem with platter is fixed, platter is running smoothly, one turn with a finger and it's keepin turning around, so the bearing of the platter is good.
Third: the wires on the tonearm are still original with the usual colors. About the yellow one: at he moment i still let him there. The tonearm has no friction and is turning smoothly... (i had a zero for parts and he had ALSO the yellow wire and ALSO cut), so i don't think it matters.
Fourth: Tonearm bearing oiling is not neccesary, as i told already it's turning and playing smoothly. I run a Empire 2000/III at 1,2grams on it. Sounds fabelous!
Concerning the motor: i oiled the two sides, and did what you suggested: takes a lot of pressure by my fingers to stop it, btw: when i start the zero manually, 33 rpm is reached in a few seconds and holding steady, no wow or flutter. I have read in the forums about startingtime over 1 minute!
So i think this is not bad...
Large wheel: no teeth broken, shows like new now...
About your second thoughts: indeed, the problem is at the starting AND the autostop.
From the moment the arm moves to the lp the platter slows down and stops. Similar at the autostop too, when the arm goes back to his base, the platter is slowing down just before he reaches his base and the platter stops.
About this: i removed at the downside a very strong spring and it seems that the problem is a little lighter now. When the arm is turning back to his base, the platter is slowing down a bit but keeps turning, so the autoshutoff is functioning now. I have put a few pictures about the spring and the part with the spring.
It seems that the problem is in this part of the automatic, but i can't locate the problem. The third picture is one i took because there is a screw in the middle but i can not make any sense of the function of it. Maybe...?
And indeed this Zero has flying from the US to Europe, i'm using a heavy stepdown transformer, but i have replaced the platterstrobo from 60hz to 50hz and also the motorpully wich is a 50hz unit, if not it's not possible to play it at the right speed.
So, it's your turn now.
