I'm not at all confident on working with PC boards like that, so I
might actually make up a whole new unit, point to point construction,
leaving the DOT it intact.

I wouldn't mind just installing the red LEDs and a new resistor in
place of the old ones, and leave all wiring as-is. I don't mind if
the LED's have a shortened life. Not too hard to replace, IMHO. Would
I still go with the 47 ohm?
