Collectors Items Now! Thanks to Modern Hearing Aids... Using IRC Resistor Elements.

For millions with impaired hearing a new avenue of hope was opened when scientists applied to this field the amplification of sound by means of the vacuum tube. From that point on, manufacturers directed their efforts toward instruments combining increased effectiveness with reduction in both size and weight.  Because volume and tone control plays an extremely important role in these small amplifying sets, it is only natural that IRC should have been consulted in the design of this sensitive part.

Unbound from a 1943 electrical engineering magazine, this unique old one-page advertisement would display beautifully matted and framed. Nice graphics. World War 2 propaganda. A fabulous addition to your retro electrical library.
