Add to Cart
<p>Original 1943 electrical trade vintage ad for <b><span style="font-size: 14px;">SOLA ELECTRIC COMPANY.&nbsp;&nbsp;</span></b>Main office and plant was located at 2525 Clybourn Avenue, Chicago, IL.</p><p> Manufacturers of Constant Voltage Transformers. </p><p>Billionettes.</p><p>Not twin, triplets, quintuplets, but billionettes, each the "spittin' image" of the one that proceeded. That is the rigid uniformity required of American arms and ammunition, a requirement which demands all the "deadly precision" industry can develop. Maintenance of production schedules and uniform accuracy in products is a difficult assignment these days. Overloaded supply lines deliver unreliable power voltages. During periods of peak loads, voltages may vary as much as 30%. Unexpected surges cause unsteady operation of precision machines and irreparable damage to delicate instruments and tubes.</p><p>Unbound from a 1943 electrical engineering magazine, this unique old one-page advertisement would display beautifully matted and framed. Nice graphics.&nbsp;World War 2 propaganda. A fabulous addition to your retro electrical library.<br></p>
