Gee everyone else's shack must have worse lighting than mine. The bulb in
one of my TT2X control boxes burned out 2 years ago and I've never bothered
to replace it as I can see the dial just fine.

| The benefit to using the 1819 is that you can get it at Radio Shack.
| One of them doesn't put out enough light.
|
| There is a solution. Buy a second socket and parallel two of 1819's.
| It then produces adequate light and spreads it out more evenly over
| the meter face.
|
| As you point out the expected lifetime is quite a bit longer.
