O.k.... so, i can happily say - no more buzz ... Amp is dead quiet.... literally dead quiet - when it is operating without signal you can't hear anything from my tweeters... no buzz, no hum........
.
I am 100% confident that, IN MY CASE, the problem was in cviller amplifier board at the input.... it can be solved by following instruction in the quote above - THANK YOU JOGI... you saved me .... (i used only resistor - no need for diodes - 4R7 resistor was enough)
...
what i will do now - i will shorten those input wires... no need to have 60cm of moderate quality input cable running inside the amplifier any longer.... as short as possible as always .... and that should be it i think....
thank you all for keeping up with me and for support and to @Jogi for his input that saved this project....!!!
cheers
Or make a whole new board.....
...
Sad i destroyed the first one i made that was exactly simetrical.....

@Jogi .. oncd again thank you... indeed it is dead quiet...
I made a review of the boards and told there about the issue i had... Jason contacted me about it... seems they will include it somewhere in the section for F5 boards in case some might have the same issue.... thumbs up for that....... it would save me tons of time if i knew that sooner
