    Well, I ran across 435 gajillion of these 48 volt telco lamps....the plug-in type they used to use for mutltiline phones and PBXs and such. Since they're incandescent, they're probably contraband. But I found out something I can do with them. I can drill a bunch of holes in a panel in the shape of letters (like my callsign) and then poke all these lamps into the holes and wire them all up like a grown-up "lite bright" thingy. Maybe I could go into the surplus telco lamp illuminated callsgn desk lamp thngy manufacturing business. Or not.

    Anyway...there's probably something I can do with these....If I ever have lots of time to do something inane.

    Now you know.

    Probably a bigger market for the signs than for a transistorized HO-10, sad to say. Especially if the signs are RF activated.

    That sounds like enough to melt all the tundra up there, you could be the 'greenies' worst nightmare.

    From what I remember of many years of changing the things when they failed, the standard 48 volt types generate a lot of heat, so I'd be fairly cautious about mounting a stack of them in friction fit holes - either I'd use a non-flamable material or, at the very least, make the panel as thin as possible to allow for maximum heat dissipation.

    IIRC, these lamps came in standard 48 volt, low dissipation 48 volt (identified by a gap between the envelope and the base), 24 volt, 12 volt and (rare) 6 volt versions - you could identify the different voltage ratings by the colour of the base as well as it being stamped on the side contacts.

    I might want to call you a lot of things, but incandescer is not one of them.

    I save odd lamps to use as components. Due to their semi-constant current characteristic they can make good series resistors in
    chargers etc, also serving as a pilot light, and maybe even a fuse.

    They can be used in clean audio oscillators also.

    Yippee ! I've got two new words for my Dictionary of New American Words. First one, incandescer, and this I like, Mutitiline, is this pronounced moo / titty/ line ?

    That's the one. I couldn't remember the name cause I'm getting old. :)
