224 RADIO BROADCAST ADVERTISER " Weighs out right capacity as accurate- ly as the apothecary weighs out a precious drug." A.C.L. TECHNICAL men were quick to appreciate Sangamo con- densers in intermediate capacities. One engineer, well known to readers of radio publications—Austin C. Lescarboura—sends us the following characteristic comment, which is published with his consent: "In my laboratory we develop new circuits and variations of old circuits, publishing the results in radio magazines. Need- less to say, we are using and specifying Sangamo condensers throughout. In my opinion there is no other fixed condenser that can compare with the Sangamo in accuracy, permanent capacity value, neatness and handiness. "The Sangamo condenser weighs out just the right capacity as the apothecary weighs out a precious drug." MICA CONDENSERS are made in 34 sizes, ranging from 0.00004 mfd. to 0.012 mfd. Sangamo Wound Condensers are ready in capacities from 1/10 mfd. to 4 mfd.; Series A guaranteed for continuous operation at 250 volts AC, 400 volts DC; Series B guaranteed at 500 volts AC, 1000 volts DC; also 12 and 14 mfd. blocks.
