Thanks, Mondial. One more question - it appears that most LEDs I have seen have a forward voltage of 2 to 2.2V at a current of 20 mA. Does the 1.5K resistor drop the voltage from 23V to 2V, or from 15V to 2V? Ohm's Law indicates that it is more in the neighborhood of 23V to 2V, is this correct?
I'm just trying to make sure I understand all of this...as I plan to utilize what I learn in replacing the Stereo Beacon bulb with an LED in my 440-T in other vintage Fisher and other receivers later on.
