Ref. post 53: The transformer will have three secondary windings, those windings are isolated from each other inside the transformer, one winding (two wires) will be for the rectifier heater, another winding, a centre tapped winding (three wires) will be for the HT feed to the rectifier, one wire to one anode, one wire to the other anode, the other wire (the centre tap) will be connected to the chassis via the 500 ohm resistor.

The other winding (two wires) is for the heaters for the rest of the valves and the dial lamp.

The wire that's left over is probably connected to an internal electrical screen and would normally be connected directly to chassis.
