And check the subchassis riding height.
A 12″ record is larger than the platter, so will scrape on the surrounding surface if riding too low.
It should have a 1-1½mm clearance with the carriage pushed all the way to the left.
Note that the weight of the carriage shifts the subchassis’ balance as it moves sideways.
This will often cause wow/flutter and/or a scraping sound at the inner tracks of a record.
No. The black lead is merely a chassis ground.
Check that you have both connectors correctly seated, one at the panel, the other (push-in ribbon cable) at the main board.
Two cables run from the muting board to the carriage.
They go under a black plastic holding bracket.
At the bracket pull the cables just 3-4mm towards the carriage – add a dap of glue to them at the bracket, if they won’t sit by themselves in this new position.
Could also have a wrong spring for the lid.
When wall mounted, the spring is to be replaced by a stronger type to counter for the increased force needed to lift the lid.
