The 1 ohm resistors are the ballast or emitter resistors for the power output transistors. The 200 ohm one is the voltage dropping resistor for the pilot lamp. It is supposed to drop the 40 volts from the power supply down to 28 volts for the pilot lamp. Sometimes people will put a #47 lamp in there and will cause the resistor to get hotter than normal. This will turn the pc board brown from the heat.
