Hi

First of all, the resistor in question is color-coded using the old body-tip-dot format. In other words, the body of the resistor is the first digit, the tip (one end) of the resistor is the second digit, and the dot or single stripe is the multiplier.

Your resistor has an orange body, no tip color, and a yellow dot (or, in this case, stripe).

Orange body = 3
No tip = Same color as body = 3
Yellow stripe or dot - 0000

330,000 ohms or 330K.

I am not at home and not near my schematics, but check the Philco Changes In Models data (available as a free download here) first. Then, if that resistor is not in the schematic or in the Changes In Models data, get rid of it. If it is in there, replace it because it is out of tolerance.

Now, regarding the 110 pF caps: Yes, replace them with your 500 volt caps and you will be fine. These, as you correctly point out, will never see any high voltage under normal conditions.
