Any led ideas to "light up" the inside of a tube amp

[jhl1963]

Looking to light up the inside of my tube amp doing daytime listening ala Macintosh. Anybody done this/suggestions?

Thanks

You might be able to find tiny LEDs that fit into the center opening on 9 pin tubes, ala McIntosh. You can then use the heater supply through a diode and suitable limiting resistor and maybe a small smoothing cap to power the LEDs. Personally I let the tubes do the lighting for me.
