Is the correct vibrator fitted? If it's a series type (as used in the WS19 Supply Unit No.2) then the coil will drop some of the voltage to one half of the transformer primary - and the centre-tap is not in the centre on that supply unit to account for this. You probably need to fit a shunt vibrator (he said, without looking at the circuit diagram).
