LM3886 troubleshooting - motorboating sound
« on: 9 Jan 2020, 08:18 pm »
Hi All,

I recently picked up a pair of self-amplified speakers using LM3886 amps.  One speaker is exhibiting a faint constant ticking sound that appears to be about 60Hz.  I haven't cracked it open yet but speculation has me suspecting the power supply

Any other suggestions to look for are welcome.
