Finished a new build. Double checked and reordered all points going to the headphone jack as I've had this popping issue before.
I'm getting a mild popping in headphones when the middle and last ring on the TRS jack make connection and am inserting the headphone jack while the amp is on.
The mild popping occurs when removing the jack and inserting while amp is on. The popping volume is louder if volume isn't set to minimum.
My question. After going over this amp with a fine tooth comb, is some mild popping when inserting a headphone jack normal for the Crack circuit, or do I need to do some more troubleshooting?
No.other issues, all resistance and voltages passed. No noise when tapping on chassis while headphone is plugged in and Amp is on. No noise when headphone is connevted and amp is turned off. Normal startup noise when Amp is turned on. Etc.
Thanks for the help!
