Turntable choices

If all you did was unplug/replug the DIN/RCA cable then check that (have a spare?), and also check the new preamplifier.

Regardless it should be a simple fix.

what miller said!!!

I've checked the turntable with a McIntosh C32 preamp and yes I'm still only getting one channel of music so the newer C47 is OK.  Next check will be a new connector to the turntable, if I can find one.

Stumbled on this.    Don’t know anything more about it but interesting.  

alaskabluesman, those turntables are getting very old and they are highly mechanized. I think it is time to put them to bed. The problem is that there are very few if any modern turntables that are that animated. There is a German straight line tracker that is fully automated and it cost $200K. 
There are some turntables with an auto lift feature which is nice but you can add that to any table. There are several good lifts on the market.
Looking at the bright side it will not be hard to find a turntable that will perform better than the B+O but not for $900.00. What are you willing to spend?
