The faint red-plate is normal... you can change the resistor
if you want. Don't forget to subtract screen current through
the cathode resistor when calculating... both go through there.
And likewise, don't forget to subtract the cathode-to-ground voltage
from plate voltage when calculating idle power dissipation.
In other words, if the plate voltage is 350 (to ground) and the cathode
is at 20V, you only have 330V across the tube.
