Hello
Hello
I have an Pass aleph volksamp 30 which I am very happy. wi For one day I have a usher 1.5.
I read the usher 1.5 is inspired by the threshold 3.9 that's why I'm asking my question here.
I have used the usher 1.5 for over an hour on my thiel cs 2.3 and it does not heat up at all. it is completely cold.
I think that is not normal.
Should we adjust the bias?
Thank you

First
Look around for trimpots on the pcb.
Take photos.
Identify the current bias point by measuring voltage drop across emitter resistors on output power transistors.
