DC voltage for 20-kHz two-transistor oscillatoris obtained from AC line, Secondaryis added to centertapρed tank coil of T1Bto provide 1 kV P starting voltage required by 96-inch instantstart lamps.Artide gives transformer and choke winding data along with circuit details and performance data. Lamps operate independently, so one stays on when other is removed.-R. J. Haver, The Verdict Is In: Solid-State Fluorescent Ballasts Are Here, EDN Magazine, Nov. 5, 1976, p 65-69.
