Lenco L85 - schematic?

Some 28 years ago my Dad gave me his Lenco L85 turntable. I never used it much and haven't used it in years.

Turned it on yesterday and there are a few problems. Most are minor, but the major issue is the pitch control is NOT working.

Any chance anyone has a schematic? I've looked at the circuit board and it is anything, but trivial. I'd like to return this unit to full working order.

try the link below - not a schematic, but the manual, which explains how to adjust set the fine pitch control (see page 9) .
