I thought I'd replace the
bigger ones, just in case, and they are whoppers.
Probably no need to replace the resistors if the PSU is working, a
simple multimeter check will tell you if a resistor's faulty or not in
almost every case.

One's [finds resistor
calculator because forgotten value] 220 ohms but about an inch long. Seems
there's lots of
1/4w ones about. No idea what wattage this one is! How do
you tell?
Experience generally although you can (simplistically) calculate the
wattage required by measuring the voltage across it then dividing
voltage squared by resistance. Round up to the nearest standard wattage.
I suspect that the 220R one you mean isn't original though if it's the
one near the heatsink. Looks 'wrong' to me.
