RE: [30MDG] Re: Reminds me of the full ashtray joke.
- I recently replaced those in my old FT-757GX (25 years old) with ultra
bright white LEDs. Since the old incandescent lamps were powered by the 13
volt supply I used 560 ohm 1/2 watt resistors which limits the led current
to about 20 milliamps. You will also have to use something to diffuse the
light. My rig had a plastic diffuser that slipped over the old lamps.
Perhaps yours does also.

Thanks Jerry, Since I am 76 probably no real problem. If I use led, would
you know the current requirement and the proper resistor. I do not have
schematic. Bob--- In 30MDG@yahoogroups.com, "Jerry Johnston"
