Why Fixed Resistance? Because it maintains the resistance values indefinitely and without fluctuation. Why Variable Resistance? Because the resistance values can be adjusted to meet all requirements. Manufactured in Canada by the Benjamin Electric Mfg. Co., Canada, Ltd., Toronto, Ontario Why CLAROSTAT Because the Clarostat combines the dependability of fixed resistance with the convenience of variable resistance. And of course there is a Clarostat for every purpose — the Clarostat Volume Control tor the receiving circuits; the Standard Clarostat for B or plate circuits of radio power units; and the big Power Clarostat for filament, line-voltage and high-power radio devices, as well as transmitting applications. Your local dealer has Clarostats in Stock. Watch the articles of leading radio authorities for data on how to build a better set or how to better your present set, with Clarostats. Or write for descriptive literature to AMERICAN MECHANICAL LABORATORIES, Inc. Specialists in 'Variable Hfsistors 285 North 6th St. Brooklyn, N. Y. Clarostat is the standard, universal variable resistor. That is why it is widely imitated in appearance, but hardly in performance. Watch for the green box and the name stamped on the Clarostat itself. Appearances, otherisoise, may deceive you.
