Hello,
Dependant on which country you reside will dictate where to get a manual.
Once you have purchaced a manual (in the USA
www.victoryglass.com may be your best bet)
I would suggest that you send the following boards to a specialist (there are only a few of us worldwide) for testing/repair:-
Memory Unit (located on the righthand side of the mechanism) 301-07855
Mechanism Control Unit (located on the lefthand side of the mechanism) 401-06905
Selector Logic (located on the righthand side of the cabinet) 601-08060
The Memory Unit & Selector Logic contain CMOS chips and are very proned to static dischange, so the boards need safe handling.
Once the boards are good you can then start on the mechanical adjustments that are fully featured in the manual, start at the begining and work your way through them, checking all the time for any wear in the parts. Replace these where necessary and only lubricate sparingly (only one drop of oil, more or less just the oil wicks on the motors, idler wheel linkage, idler weel shaft and turntable shaft ) where indicated.
Please let us know how you get on.
Regards
Alan
