PuhPow, in your original post you indicated you have recapped the radio. I'm not certain but it seems like you found the resistor burned, was it burned prior to the recap? I only ask this as if it was you more than likely fixed the problem with new caps. Having had the radio come to life with your 1/2 watt replacement sounds great, the fact that it burned out is not surprising, very underrated.
When you get your new resistor I would bring the radio up on a dim bulb or variac to be safe and monitor on your meter the B+ voltage on either side of the 300 ohm to see if it comes up and holds.
