I assume the TG66A Oscillator meter needle should be at the left hand side of the meter display but the nearest it gets with the mechanical adjustment screw fully in one direction is as per Photo 2, Photo 3 shows the meter needle position with the adjustment screw fully in the other direction.

So am wondering if this is a fault and if so the likely reason.

The unit arrived with no mains lead and the mains connector on the unit was a large Bulgin which I ripped out and purchased a IEC C9 connector to fit in its place then to use with a kettle type mains lead. But the C9 connector is currently hiding somewhere so not able to power up to see if the meter needle moves when signal is present.
