I am surprised, cause I do not have any hum even though I have no grounding(it is in tweaking mode — on the floor with no chassis :-). Opposite to my Aleph.

Without inputs connected, I hear very light (passes the test), I really have to touch the ear to the column.

Input connect only on the left side of the column is silent, but the other is with a slight buzz. Input connect only the right side the same thing happens.

When I connect the two inputs hear the buzz in the room, all this with zero potentiometer pre course.

Much has been said here of buzz, but I think every case is a new case, so thank you for your help.

This scheme reads:

A cable Qed mesh connected between IN and pcb channel. The mesh connects to GND.

The GND Speaker Out connects to GND PCB Canal.

The GND of the PCB connects to PSU.
