Power Transformer Wiring (Big Iron Part IV)

After some discussion about the valve heater wiring connectors, me and Vin* (the guy who designed the kit) agree that this is the correct wiring for the power transformer. If you disagree, please leave a comment before I get round to plugging it in!  

Left, top to bottom:
red - HV secondary                              TO V6 PIN1
red - HV secondary                              TO V6 PIN7
grey - HV primary                               TO MAINS (NEUTRAL)
yellow - 6.3V rectifier filament secondary      TO V6 PIN4
green - 6.3V filament secondary                 TO MAIN VALVE HEATER WIRING

Right, top to bottom:
red/yellow - HV center tap                      TO GROUND
black - HV primary                              TO POWER SWITCH MAINS (LIVE)
yellow - 6.3V rectifier filament secondary      TO V6 PIN5
green/yellow - 6.3V filament center tap         TO GROUND
green - 6.3V filament secondary                 TO MAIN VALVE HEATER WIRING

*Don't worry Vin, I won't hold you responsible
