Christian, when I was restoring the HP Computer Museum's 2116A I ordered a bunch of these 345 bulbs from 1000bulbs.com - but it seems they no longer stock them.
I did find this listing though which looks current... https://www.lighting-pros.com/eiko-345-t-1-3-4-midget-flanged-sx6s-case-of-1 0 They are around 0.04A current draw - not 0.75A!

The old/original ones are CM-345 or OL-345. This makes sense, they are rated 6V 40mA 10000 hours. BUT: The maintenance manual says something different and is even wrong and inconsistent. HP part number is 2140-0035, description "Lamp, Incadescent, 6.3V, 0.75A" This can't be true. 92*0.75A would be 400W alone for the front panel lights... The manufacturer code is 71744 (Chicago Miniature Lamp Works), mfg part number 1775. That is indeed a 6.3V lamp, but 0.075A (better!). Problem: that is a midget _screw_ base lamp, so wrong socket and only rated for 1000h. The panel and switches need a midget flanged base lamp. Who wrote that manual? Was he drunk? ;-) Christian
