Default Resistor not the same as schematic

The problem is that resistor is red red brown @ 5% (gold).
That's 220 ohms. Yet an online schematic shows R601 as 100K.


Think about that for a minute. How is any of the 44 volts
supposed to get though a 100K resistor and be able to do
anything?

Replace the 220 ohm resistor with another 220 ohm.


Better first find out why the other one blew. It is likely that
a decoupling cap (tantalum?) downstream has failed.
