CURE_FOR_NOISY_CONTROL

Published:2009/7/2 3:14:00 Author:May | From:SeekIC

Connecting 5K resistor between grid of first AF stage and ground as shown substantially reduces noise generated by worn volume-control pot in older tube-type communication receiver. Modification can be made from top of chassis by wrapping piece of wire around grid pin of audio tube, bringing wire up alongside tube and out through top of shield. then soldering 5K resistor between wire and chassis.-J. Schroeder,Temporary Fix for Noisy Volume Controls. Ham Radio. Aug. 1974. p 62.
