what is wrong with ZPA 0.3 V1

[demosta]

So guys. Can you help me with my ZPA?

Problem is a distortion, a lot of distortion.. Right channel sounds very clean and nice, but left channel doesn't. When i play music quietly it sound nicely too, but when i raise the sound level, music becomes very very distorted and the same time yellow thermal led blinks.


So right channel works perfectly and left channel doesn't.

The left channel distorts at high volumes, likely due to a thermal issue—yellow LED indicates overheating. Check for faulty components or insufficient cooling.

sometimes it is just a dirty gain pot that can be cleaned by swiping it back/forth when it is turned off. Try turning any nob you can, just take note where it is prior to starting and put it back at that point.
