Hi, best groove
It was a cut caused by a scrape that was under the solder mask, so a manufacturing issue. Nearly the entire trace was cut, except one small corner at the edge of the solder filet, which cracked right at the very corner causing the intermittent connection.
The MN6042 is used in every Technics table that has digital pitch control. You are correct - not the SP-10 MKII.
