My 10C ran for years with this resistor jumpered. I used one from a degauss circuit. Seems to work OK. Just makes the set a bit slower to power up. This resistor is the main reason that my set was dead when I got it in 1974, After that, the kine got broken, and somebody wiped out all of the tubes. Then I got it.
I have a feeling that this resistor eases the start-up surge through the diode power supply.
