The instructions listed the #40 6.3-V, 0.15-A flashlight lamp.



However, a lamp that lights up at the lowest possible power gives you
maximum sensitivity and distance from the transmitter. The #48 lamp (2.0
volt, 0.06 ampere, 33 ohm) is the most sensitive incandescent flashlight
lamp I have found.



In fact it will burn out if you get too close to the transmitter,

Anybody know the specs of the light bulb in the old polarized radio wave
demo? One of my faculty members dropped and stepped on the receiver antenna.
Guess what got crushed.



If you have .pdf of that manual, I'd love a copy!



Thanks,



Sam
