Perished "rubber" mat , the generic replacement one I replaced it with

not working with the 3 IR ? LEDs for automatic monitoring of presence of

differentiates between mat and vinyl. Or is there likely to be an
adjustment
under the deck?, the ,new to it mat, looks decidely matt to me, compared
to
glossy vinyl.

Doesn't the old mat have several holes coresponding to the size of the
record, and photocels beneath the platter?

Now I have it back working fully, there are 3 ordinary red LED under the
platter and 3 LED looking opto-trannie/diode? receivers above, on the lid
section.
So just masking off them and taping down the cover closure microswith allows
exposed to work on operation.
