Burnt screen grid resistor, my mistake.

[Mr.Death]

I was checking bias today with my new probe and when I reinstalled the tube I installed the tube incorrectly, the key was off by one pin. My mistake and I'm ashamed of it  .....  I ended up burning one screen grid resistor in the process. When I inspected the amp I noticed R30 (1K 20watt sand resistor) was hot to the touch and a little discolored. It measured fine with the multimeter. I ordered the 2 47R resistors for the screen resistors. Should I also replace the 1K20watt? Like I said it still measures within spec. Leave it? Thanks. Schematic for reference. Resistors circled.

I never like to leave burned or overheated components in an amp.  What happens when it is under load again?    Just replace it as they are cheap.

[Mr.Death]

Just happened this morning and Ive yet to replace the components. Having a hard time locally finding a sand cement resistor for the 1K 20 watt.

[Mr.Death]

I replaced the burnt 47r resistor and everything works as it should, lesson learned.

I installed the tube incorrectly, the key was off by one pin.

How did you do that unless the key on the tube was missing?

Glad the damage was minor.
