F5 buzzing issue

Because i did not want to use it but instead, i used just a 100uF capacitor to put it in paralel with the rest at outpu of the CRC.... there is no place on that universal board where to put smaller caps say 1000uF and some MKP's if you want.... only couple of places for snubbers (that i don't like to use) and big cans.....
...
Connection on chassis on picture bellow....

You can not use the snubber positions to bypass your cap bank. I believe you have shorted the PSU with that link instead of a resistor. The Burning Amp 4 is non existant amp, but a potential for all builders when shorting things. Bad joke, sorry.

It is not shorted.... i already teszed the psu, all is good.....
That snubber circuit is resistor in series with a capacitor.... if you short the resistor part, you don't get a snubber circuit but a cap that is in paralel with the big cans.... nothing new there, all good..
Besides, that 100uF there is so small that it does not need bigger traces so all good there too....
 
No need to worry... all good.. cheers....
..i am more worried about ground loops and that buzzing issue...
Hope with those traces cut on my amplifier board and with HBR resistor in place it will be finally silent enough.....
....
On my psu - those secondary wires are very hard... will not be able to twist them enough so i will use those plastic things (don't know the name on english) to hold them together and also will attach them to the psu board using those faston pins.....

I am not happy having such a long input wires going all around the box like suggested....
Also i am not happy having signal going together with power supply wires... but it was suggested to do ot this way.....
I would be super happy to put away the signal from power supply and to shorten the signal wire.... here i have more then 60cm of signal for the right side..... that is more then my interconnect going from my preamp to F5..... not happy....
Oh well...

Since you are making a new supply, my suggestion would be to reset the amp boards to their original specs, and wire it like a First Watt amp. Then consider tweaks as suggested. Since all good suggestions are allready implemented, finding the source of potential troubles may be impeded. On the other hand,
It should be quiet now. Though, signal and DC should not be mixed, I agree.

Thank guys.....

I doubt the problem was my power supply board... as always i made tweaks, everything pointed at the input of the amplifier to be the source of that buzz....
So, i hope now, since i cut those gnd lines at the input of the board, it will work....
Next thing would be for sure to instal the input wires directly and as short as possible to see if it will work this way... i don't like that these wires are so long.....
From what i know if you must cross signal and power supply, you do it as few times as possible and on 90 degrees angle.... here, my right side is going directly along the power supply wires which i don't feel is right but smarter guys then me said to do it, so i will have to see if it will stop buzzing finally....
