This doesn't directly answer your question, but for my 3000-1, I
pulled a white LED out of my stray parts box and soldered it into
the base of the burned out bulb. I put a thin white paper cover
around the element to disperse bright but narrow beam thoughout
scale tube.


I'm not familiar with the 3000. But, if you need to disperse the light from
an LED you can "frost" the plastic lens by lightly scuffing it with a piece
of fine sandpaper.




Which works well in most cases. Not so well in this case, because
of the narrow angle of the emitted beam and the fact that the LED
is at right angles to and behind the surface to be illuminated. Even
after frosting, most of the emission is still wasted on the left
inside of the radio.

Now, for an LED that radiates head on, like a pilot, or in the
case of my Marantz 2218 stereo beacon, yeah, buffing the LED with
light sandpaper or steel wool does a nice job.
