21 pages from "Quartz Crystal Oscillator Circuits Design Handbook" by D. Firth of Magnavox Company, Fort Wayne, Indiana. This epic was published in March 1965 and this chapter contains everything I need to know about how to build a low frequency crystal oscillator using valves (tubes). Many thanks to Len Anderson for sending me this information.
