Hi, I have a Beogram 3300 that was working, but hadn't gotten much attention for the past several years. (I've owned it since the late 1980s; fell in love with these tables in 1978 and finally got one). I tried spinning a record and the right channel was missing and there was buzz. Sure enough the ground wire had slipped off the preamp. Fixed that, still channel missing. I have a DIN to RCA adapter with separate ground lead. Popped the RCA plugs off, ran signal from an iphone into the phono input at very low volume, confirmed preamp fine, reconnected B&O RCA plugs, put a record on, sat back to listen. About ⅔ of the way across, the tone arm started skipping; it would not go further across. I got the arm up, tried to shut off, and the entire mechanism froze. The sight light was still on. I unplugged, and the platter is frozen in place; somehow the mechanism has locked, but the main drive spindle still spins freely. I've been advised to give up, no one bothers to fix these anymore, thought I'd just post up here to see if anyone has any ideas. It seems like it was so sudden that it's some sort of mechanical issue where the mechanisms got bollixed up and might just need a nudge in the right place. But I've been as far as getting the platter off and looking at things and there is nothing obvious and I'm afraid to break something or get too far in and not be able to get it back together.

Any thoughts appreciated.
