I ended up using warm white LEDs and they came out pretty good. The lights for AM FM indicators are the same as the bipins Used in the phase linear light boards. I had the bulbs I needed except for the dial indicator. Used a LED, a 1N4004 diode and 470 ohm resistor. It fit perfect and did a good job. After thought was, I could’ve used a blue LED which may have looked better. Got it done, it works, on to the next project.
