Wax nostalgic about and learn from the history of early electronics. See articles from Radio-Craft, published 1929 - 1953. All copyrights are hereby acknowledged.

Here is another one of those advertisements that you would probably never see in today's electronics magazines, but its theme was fairly prevalent up through about the 1970s. There is fundamentally nothing offensive about it; men have always endeavored to gain the favor of women. However, society has since been bullied by name-calling, finger-pointing, full-of-themselves celebrities and media into being afraid to acknowledge innate, harmless propensities of everyday people. The natural has been declared unnatural and nonbelievers must be reprogrammed to not just tolerate, but to encourage and facilitate counterintuitive concepts.

Mallory Carbon Controls Advertisement, March 1948 Radio-Craft - RF CafeUniform Resistance

Mallory carbon controls are accurate in overall resistance value

You will find no variation in the resistance values of Mallory carbon controls. Frequent, critical inspections reject the imperfect, and pass only those carbon elements of the resistance values specified on the labels.

Recently dozens of controls from leading manufacturers were tested competitively for overall resistance value. Mallory controls averaged within 2% of specified resistance, the closest tolerance of any group in the test.

In volume controls you look for uniform resistance, accurate tapers, silent operation and long life. Mallory gives you all four, and more, too. The Mallory trade mark is your assurance that the volume control, vibrator or capacitor you buy is the finest that can be made.

The Mallory 1485 Control Deal

This attractive metal cabinet contains the 15 Controls and 9 Switches that will take care of 90% of your service calls. Its arrangement makes inventory control almost automatic - saves you frequent trips to the distributor's counter. It contains a rack for your Radio Service Encyclopedia. You pay only for the Volume Controls and Switches; the cabinet is included in the deal at no extra cost to you. Check your Mallory distributor on this special offer.

Every carbon element that goes into Mallory controls is individually inspected to be sure that its resistance value is the same as specified on the labels.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
