Ok…..check this set of switch contacts also…I know i keep banging on about switches but if nothing else you will eliminate them from the search. If these contacts dont operate your motor wont operate as a servo, the contacts should open when the solenoid energises

Already checked those switches…  Thought they would be OK as it all works when playing a record… Just that it will not work in either Reverse (RE) or Fast Reverse(FR), which makes me suspect the logic inputs to 1TR34…  I’ll be checking those first.
OR – If they are OK then the circuitry around 1TR34 could be faulty.
