The smaller one is a 2W fusible resistor. It's made out of ceramic and is designed to take the heat. After a while though, I discovered that the solder was melting!
Probably should use a high temp solder like silver solder.
It's drawing about 400ma so I figure that little 4.7 ohm resistor is putting out less than 1 W.
I decided to just use one of those old 7.5 ohm globar fuse resistors and locate the diode near where the older selenium rectifier had been.
