You need to answer these questions:
1) Switch it OFF!
2) Did ANY of the valves light up when you had the magic eye disconnected?
3) Please confirm the valve in the socket 2nd along from the mains transformer is a UL41
4) Measure the resistance from the UL41 pin 7 to chassis
5) Measure the resistance from UL41 pin 2 to the terminal of the big electrolytic capacitor with the red lead (goes to the UY41) but no resistor
6) Confirm you have replaced the wires to the output transformer

I am still looking at the other voltages but you have quite a few problems so don't power it up again until we have checked the wiring.
