AC
mains connected to the fuse and then to the power switch and finally to
the power transformer primary. The standby switch is wired to the HV secondary
center tap through the red/yellow wire and to ground through the black wire.
Also, heater wiring is shown as twisted green/black wire. |

The
green 6.3vac wires from the PT secondary are connected to the pilot lamp
then jumpered to the hum reduction resistors via the twisted green/black
wires. The twisted red wires are the HV from the PT secondary connecting
to the full wave rectifiers. |
