Soft hum at no volume in tube clock radio
I just finished recapping my Panasonic 720 tube clock radio (circa 1964). After doing some initial tests and cleaning the pot and switch with DeOxit D5 and F5, I noticed a soft hum with the volume turned down. Is this normal? I was just wondering if inexpensive radios were more prone to hum at low volumes than better-made radios. Also, could the clock motor introduce some hum to the radio circuit?
