Philco 87 alignment question/RESULTS
01-21-2012, 08:18 PM
The "volume control" on the 87 is just a 10K potentiometer connected between the antenna terminal and ground. On sets like these, a good ground is essential for proper operation of the volume control. Left ungrounded, the volume control is not always effective on strong local stations, as you have discovered.
