Model 41-250 Band Lamp
#4

I posted this description of how the dial cord is routed for the bandswitch lamp on another thread. Sorry it is so wordy, but I hope it helps.

Quote:I just took the chassis out of a 41-255. It has what I think is the same arrangement of the pivoting lamp assembly.

It wouldn't photograph well because the spaces are so tight, so I can only describe it in words. This is what it looks like to me, without disassembling everything to look.

There is a pulley on the band switch shaft in the front of the chassis. There is a wire cord guide riveted to the chassis to the right of the tuning knob shaft. The cord goes around the pulley and through the hooks on the cord guide. The cord coming off the upper side of the pulley goes through the upper hook and so on.

The cord coming through the lower hook goes up and around the inner of the two races on the pulley at the top right behind the dial glass. (The dial pointer cord goes around the outer of the two.) The cord then goes down through a hook bent into the sheet metal on the right side of the lamp assembly and then ties onto the tensioning spring just below the hook.

The cord coming through the upper hook goes up and ties directly to the lower side of the tensioning spring. On mine, the bottom of the spring is about 1.75 inch above the wire hook and the top of the spring is just below the sheet metal hook on the side of the lamp assembly.

My guess is the you can do this by taking out the near XXL tube and rotating the lamp assembly backward to expose the sheet metal hook on the side. Tie the cord to the spring and pull it tight through the sheet metal hook just above the spring, up around the pulley at the top of the dial, down to the lower wire hook, left around the bottom of the band switch pulley, right to the upper wire hook and finally up to the bottom of the spring. Pull it tight, stretch the spring a little bit, tie it, and you're done.

I know this is long and hard to follow, but I hope it helps. Write questions if you need to.

Oddly, my 41-280 doesn't have this pivoting assembly but has 3 lamps that are switched by the band switch to illuminate the band identification, plus one more to light the push button station IDs. My 41-250 and 41-255 both have the pivoting lamp assembly.

The schematics for all three models show the 4 switched bulbs.
