Hi, all.
I have some weird noise from my crack. When I turn it on, it is dead silent, but after 20~30 seconds, it starts make some noise, and it sounds like mixed of static noise and squeezing Styrofoam.
I checked if it is any connection or assembly issue, but no luck. (It happens regardless input cables are connected or not, even without tubes)
Maybe, I will try reflow or re-soldering the headphone jack part, but is there any other recommendation that I can try?
Looking for your advices, and thanks in advance.
