just measure the voltages. remove the 100ohm resistors for now, and fire up the amp and measure the voltages between the green filament wires and the orange wire. if orange to green measures 3.15V then that is the center tap for the heater winding. if you are going to use the 100ohm resistors then you should lift the centre tap of the filament winding
