At the picture is top view of finished PCB.
At left are air inductors, but I tried also with toroide inductors from old computer power supply, and with some other inductors, but problem was always the same
I built this amplifier. I have used the same PCB as in the case of @ Primoz.
What kind of heatsink did you use?
It is not clear even in the datasheet.
How do you mechanically mounted the heatsink?
