Hi Vojtech,

Thanks for the reply.

"neutralisation" is a nostalgic word.
I hadn't been aware for years.
It filled few pieces of the puzzle.

Thanks also for the explanation of the traps.

I tried to improvise, but I burned 2N7002 and BS170.
even MOSFET is more clitical than I imagined.
fixed resistance is seems too rough for bias and VR is needed.
