Dave, I have a Livermore 76B:
Nice! My 71B is very nearly identical to that, except the left switch on the rear has three positions, instead of two. I don't recall what the other position is offhand.
In mine, the two lamps on the front were those cylindrical aluminum incandescent cartridge bulbs, both of which were burnt out. I couldn't get replacements at the time (I was ~13) so I replaced both of the bulbs and their sockets with LEDs, padded with some hot glue around them.
Maybe the lamps on mine are just burned out. I'll have to check.
I'd say it's likely. I've seen no docs for these, not even on Bitsavers. It'd be nice to know the specs for those lamps. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
