FOR TRANSISTOR CIRCUITS
Lafayette brings you the answer to the problem of the low output inherent in transistor circuits, where the power is so
low you cc proof afford to lose any of it. You'll be amazed at the difference in volume when you use this now dynamic
earphone. Extra efficient construction with a powerful magnet gives up to 3 times the volume of other dynamic ear-
phones, and at the same time gives you the quality of reproduction that is possible only with a dynamic unit. We've
tried it on all kinds of transistorized circuits, and this remarkably efficient earphone preserved the precious power so
well that in many cases the program was plainly heard with the earphone 2 feet away from the ear. It is not, of
course, limited in use to low power devices - it will give superior performance wherever a high impedance dynamic
earphone is required. AC impedance 8000 ohms, DC resistance 2000 ohms. Comes complete with 3 ft. detachable
plug-in cord.

The latest version of this famous cad-
mium sulphide crystal features greater
stability, greater sensitivity at low
voltages, lower noise level and longer
life. Highly pure cadmium sulphide
crystal extremely sensitive to light
over the entire visible spectrum, with
maximum response near green portion,
usable response in near infra red, and
exceptionally good sensitivity to hard
X rays and gamma rays. High output
voltage and relatively high output cur-
rent. Will operate a meter, a relay,
neon lamp, cold cathode gas triode.
It will drive common receiving tubes
to full output at low frequencies, Ideal
for constructing exposure meter, for
quick relay action, etc. Sensitivity is
