I got a mint Dual 621 turntable with a Grado cartridge that sounds fine.
The tone arm is supposed to be fully automatic. But it no longer moves
over to the beginning of the record when starting it, nor does it move
back to the right when it lifts at the end of a record. It will just go
up and down. It plays as a manual TT, but I want it fully automatic
again.

How much of a pita is this to fix??

Hi David, did you have any luck in fixing this... coz I have a same problem.
Unfortunately the Service Manual that I found on the net is in German.

There is a plate that moves back and forth under the arm assembly. A
pin with a rubber boot presses against the plate. That boot can wear
out. Back in the day, I repaired thousands of Duals but I have no idea
where you could obtain the boot today. If the boot is still there you
could try cleaning the bottom of it and the top of the sliding plate.
Put a thin layer of GC Phonolube on the plate and let it cycle for
awhile. If you are lucky, it will begin working again.
