Default Dynatron music centre.

I have a Dynatron music centre with a Goldring G101 turntable.

It seems to be running slow, I have replaced the belt and lubricated the motor, but when timing the deck 33 is at just over 31, and 45 at 43. Any advice please?

These decks never ran at exactly the correct speed even when new. For a 50 year old deck your measurement shows that it's holding up quite well. I suggest you get double check all the linkages and the alignment of the motor mounting. It might also be worthwhile to try to source the Service Manual.

Does the new belt have a triangular cross section? As I understand it, square section belts don't work as well in this turntable.
