#51 lamps and the newer bulbs.

[Babybearjs]

well, I went ahead and ordered some 12PSB bulbs from 1000bulbs.com. they came today, and just like I suspected, the specs are off just a bit. they will get used, but not on the phones... they won't fit all the way. they are just a tad too long. Knowing that the #51, 52 lamps are still out there... where can I find new ones? the original part number was a 10PSB and the 12PSB was suppose to be the same size. the only difference was the voltage... at least the tolerance level anyway.... (both bulbs are really the same voltage, 12 volt) anyway, who still makes the #51 lamp? anyone know?? the brand I went with was Eiko.
