The reason I prefer the incandescent lamps isn't a color thing, so amber or yellow LED's don't do it for me either. It is a spectral issue and the way the light emits...the LED's have a sort of pulsating effect that can be seen when my eyes move across the device with the lamp...and the narrow spectral content just doesn't look right. Can't stand them actually. All TOTALLY personal preference, and yes incandescent lamps are more expensive and have MUCH shorter service life so there just is no practical reason AFAIC to NOT go with LED's...I think the LED's do look pretty neat for a number of things and many folks prefer the look...its just not for me. My Ampex meters have to have that warm glow of the incandescent lamps.
