Have you ever had the problem with the Lab-80 where neither the "Auto" nor the "manual" paddle switches will stay on?? Nothing seems bent-most of the old visible grease has been cleaned off from the various levers and arms on the underside of the turntable. I am the original owner of this turntable, it always ran very well, packed it away-now neither of the power switches will not stay in the "on" position. Any ideas on some adjustment-particularly with the main cam- that would cause the two power levers to not stay on?? Any advice would be greatly appreciated. Where did you order the teflon to make the bearings?? Sounds like a great solution to improving the LAB-80. Thanks-Cheers-Dave
