Agree with all, if the resistor is not discolored or shorted out, it probably is fine. I've done a number of the 46 and 48 portables, and they are great performers.

My suggestion would to bring this one up slowly on a variac and measure the voltage on the filament string. It will probably be too high with today's higher supply voltages and your recap job. And if the rectifier fails and you replace it with a a diode, definitely you must beware.

I have added a couple of hundred ohm 10 watt resistors to the string of the filament supply to tame this down with the original rectifier in place and have had good luck with it. You would want to dress this close to the chassis as it would get warm.
