In Reply to: Thup-thup-thup and static coming from my power amp posted by Wilbur Pan on December 12, 2016 at 14:17:41:
Had static and occasional thup in a preamp. Swapped parts until I located it in a pcb I had re-worked. Bad contact.
If it's in both channels it could be the power supply..... not sure why it migrated.
In my case it was in a sensitive part of the circuit - the preamp. Noise might be more obtrusive in the input, but who knows with these things.
Bad contact is my guess.
