Wonderful board, good info, been reading posts since I acquired a used 4004 last September. Read about the horrors of sending these through the mail and winding up with wood chips and shrapnel so I was lucky that the seller knew how to pack. But I'm off on a tangent. A few weeks ago my 4004 would not move the tonearm after initially setting it down on the record. I opened it up (thanks to board members that showed how to do this!) and noticed that for the fine motion needed to move the tonarm, the servo was turning but the belt was not. Easy fix - just get a new belt. I checked on the board and fornd that LP Gear was a recommended source for the belt. I ordered one and about a week later it showed up.
Finally to my question. The replacement looks much smaller than the original one. I read elsewhere on the board that belt diameters are not readily known so I have attached a picture of the two. Is this the correct size? The new one fits tautly on the pulley and needed to be stretched somewhat to fit over the servo motor. With the new belt the tonearm transport is rather noisy. Does it take some time to wear in? I have also attached a picture of the drvie mechanism.
Thanks for your advice
