Used as signal source for identifying particular wire at midpoint in cable, for splicing. Ends of wire are connected between A and B, to become part of parallel-tuned circuit of astable mvbr. Tiny probe coil with amplifier is then used to locate wire carrying 20-kc signal.-J. S. Rushton, Probe Identifies Cable Wiring, Electronics, 34:9, p 51.
