In Reply to: SET headphone amp hums posted by aarocks on August 25, 2016 at 05:11:09:
You have an amp with an electrolytic cap failing in the high voltage supply. This is not unusual with low cost chinese electrolytic capacitors. This amp should not hum. They quote a 90 db signal to noise ratio. Your's is no where near that and is defective.
