Re: SX-110 Dial Lamp Mystery
|
I can only guess that there was a design update but they forgot about the lamps. As they were built the person installing the lamps did so without being told not to. Then got to the next step and that builder just let it be.
That's only a guess.

All, ? In the SX-110, there are two dial lamps for the bandspread slide-rule dial. Both of these lamps are at the base of the dial plate, and they mount behind the front panel (see circled lamps on photo). However, in actual operation they don't really provide any light to the slide-rule dial (see photos 2 and 3) because at the very bottom of the dial area, sandwiched in-between the chassis and the front panel is a spacer. The spacer belongs there -- it provides the correct spacing between the front panel and the dials.
So, in effect, those two dial lamps aren't really illuminating anything except themselves and the backside of the front of the chassis. The two holes the lamps stick into go nowhere except a dark hole.
Was this a design flaw with the SX-110? ? 73 ¨C Steve, KW4H
