From experience, you may need a full set because if you replace just some of them the brightness of the new ones will probably be noticeably different. Slothie reckons modern displays produce a lot more light per mA than equivalent displays from 40 years ago.

Going way back to near the beginning of this thread you did say that in your recollection the segments on the big display had always been dim, at the time you seemed to feel that you had possibly not got the display driver design or component values right originally?
