Do not be so concerned with the voltage on pin 3 of the 6K6 tubes. It can go to 315 V or more safely. What is really important is the voltage on pin 4, which is the screen grid. If the voltage on pin 4 is around 250 V or less then you are fine.
Check this voltage on pin 4 as I believe there is a dropping resistor which reduces the voltage to it. It appears Philco ran a higher voltage on pin 3 but reduced it on pin 4 so the tubes operated within there ratings.
Any power resistor that is not heat sinked to the chassis will get too hot to touch. They will reach several hundred degrees at their rated power and is perfectly normal.
