OK thanks. I figured it must be there mostly for noise reduction. It was suggested to me (on another forum where I asked) that such a resistor was rather unusual, and while its presence might have something to do with noise reduction, with an unpolarized plug its got more chances creating a dangerous situation of having line voltage on the chassis, and I probably should remove this resistor and make the 6V power supply completely independent from the mains.
Since I'll be working on this radio I think I'll just take the resistor off the board for now, see if it affects the radio in any way, I can always solder it back if needed.
Thanks!
