Yes..
The original problem was in faulty wire-wound potentiometer, the wire was broken on one place and when I was turning the knob the wire touched the metal enclosure of the potentiometer, so the processor input was put directly to 340V and consequently destroyed..

After replacing the pot with new one, the second board works as intended.
