Neil,
I have used bright blue LEDs in my R4A. I took out the white reflector
and re sprayed it white. I then shone the blue LEDs (two of them) into
the quasi parabolic diffuser. Suited me.

I am again trying to find some solid tubes. I have seen none advertised on
here for quite some time and wonder if anyone has any lying around that they
would like to part with for the B or C line.
Speaking of which... I've wondered how hard it would be to make some
things like this (assuming, for discussion, that you could get some
appropriate 7 or 9 pin bases to build on)?
Diodes are obvious, and I suppose an FET could be rigged to work as a
triode, but how would you replace a more complex (multi-grid) tube?
Dual-gate mosfet or some combination of parts?
Also - anyone tried using bright blue LEDs instead of bulbs + blue
filters for the dial and meter illumination? My filters are shot...
