Wouldn't worry about the IF coil more than likely the 47K resistor has drifted some but is of little consequence. If I had it apart to replace the rubber wire I'd check and replace. But the 4 ohm/80 ohm resistor is an issue. 5w is ok total dissipation is 1.8w, I generally go X3. Dissipation is less for the 40 ohm (abt 1 w), it's job is to stop the lamp from burning out from the ac inrush.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
