Marty; here's what the service manual say to do:
1. Remove top and bottom covers.
2. Pull off all knobs. Unscrew ring nuts on mic jack and tuning
shaft. Dealer may need to do this with a specail tool.
3. Remove small screw on PC board just left of mic jack
4. Remove PC board
5. Replace bulbs. Rightmost bulb has sleeving on wires.
6. Put it back together.
Let us know how you come out. I'll probabily be doing this procedure
myself very soon. Dave WA0ZZG

> Subject: [Yaesu] FT-5100 Bulbs
> Hello out there in Yaesu land. I was wondering if anyone has replaced
> the bulbs in their 5100 and how they did it. I have heard several around
> town here say that they burn out quick after replacement. Also seem to
> remember someone mention, but cannot remeber where something about using
> LED's instead of the 10v grain of wheat bulbs used by Yahoo. This unit
> is on constantly in the house and the original bulbs lasted about 5 or
> so months. They have been out now for about a year. It isn't a big deal,
> just would like it to glow in the dark again. It can be a pain when I
> have to turn on a light to see what freq I am on.

> Thanx, Marty N8MG
