Imperfect copy: cover missing. Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references. “This report describes a versatile all-solid-state power oscillator originally designed for use with an ultrasonic agitating system. The unit produces a variable frequency sine wave (25 to 100 kc) with a power output of 20 watts into output impedances of 8, 8,000 and 10,000 ohms. The circuit is completely protected from short circuiting of the output"--Abstract, p. i. Includes abstract in French. gccst Electronics gccst Design Bettens, A. H. Canada. Natural Resources Canada.
