I disconnected the red wire and the resistor does NOT get hot.

The red wire connects to a terminal that has a 150 ohm resistor connected to it. The other end of the 150 ohm resistor connects to a terminal that has the 250 pf (#22) cap connected to it. This design is seen on all of my other 40-180 units.

Bad #22?
