Yes, as Richard stated please replace that power cord. You can buy a 8' or 12' extension cord and cutoff the female end for a quick and cheap replacement.

Doesn't the service document you downloaded have the wattage listed for that 400 ohm resistor? If not I'd try something like a 25 watt chassis mount to dissipate heat. My guess is someone put in that big pink 400 ohm because the original went open or was getting very hot. Replacing the Selenium rectifier (if bad) might correct that.
