Congratulations on getting it going!
If it is designed as a continental set/220V mains, it may be that the scale lamp runs bright on higher UK mains. Heater voltages of the valves would quickly indicate how close to spec. in the printed manual your voltage checks should be. Eg the UBL21 should have 55V across the heater.

PS please remember this is a live chassis set so observe the safety precautions necessary - especially ensuring that the mains are connected right way round so chassis potential is close to the earthed side of the mains and not the live side.
