Re: SX-110 Dial Lamp Mystery
|
Well, this particular SX-110 appears to have been untouched since being built, and it was even stored in the original box and came with an original service manual.? The factory seal was still on the bottom of the cabinet. ?Nevertheless, I think I¡¯ll pull the front panel off to see what the heck is going on behind there.? I agree with you ¨C the lights should shine through.? The spacer (what I can see of it) appears to be solid. ? 73 ¨C Steve, KW4H ? I am not sure but could someone have replaced the spacer? Could the original spacer been clear and now it isn't. I assure you the dial should be lit.

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
