My Sharp JC-77 was playing very slow so I replaced the belt with the correct size and she is still playing slow.  Does any one have a manual for this unit.  I can't seem to find the speed control on the board.  The auto reverse also will not engage.  I love this unit and want her up and running.  Please help.  Or maybe you have one that you have fixed let me know.  Are these that rare?

Thanks
