When building the F5T V2; will this ECE-T1HA273EA Panasonic Electronic Components | P10633-ND | DigiKey cap be OK or will it be an overkill?
I am thinking of using Teabag's boards, so that will mean 4 caps per rail.

Thank you for the feedback.
BTW, my wife is going to kill me with all the parts that I have been ordering lately.
Hahaha...same here !
Tip: I order everything in small portions, so the total amounts are low....
Oh, sorry I wasn't clear which board I ment... It's this board I'm referring to...
And yes, I wish they were in the DIYAudio store
they are 73*70mm

I wish you a long and happy life and marriage, but OTOH that coroner's report would be real interesting reading, if it was actually 'with' the parts.
I will be using two amplifiers in one monoblock, running in balanced mode. Per side we will have 8x 10,000 and 8x 22,000uF caps. I know there are enough people running lots more, maybe twice or more the amount in the official schematics.
I ended today my F5 Turbo v2, the sound is fabulous, I gained more dynamic and bass QB, but ... the HUM not let me go.
I need help because I can not stop the hum, I begin to suspect that the apparatus is doing pre!
I'm using the pre-out of RA1520 Rotel integrated amplifier, takes little time and is still under warranty, you may be pre??
Already with F5 std had buzz, did all experiments and then some, and softened a bit, but there was always a little bit, but now we hear this a lot ...
I'll tell you how I have the F5 V2 Turbo:
- The PCB source was made by me and the layout is just like the NP. No more and no less pieces.
- The IN is done with cable Qed with attached mesh will GND the pcb.
- The mass of the Speaker also connects to the pcb along with the GND.
- Then comes the pcb a wire that connects to GND PSU.
- PSU with 16 capacitors CDE 15,000 each, and resistance Fukushima
The same thing was done for the other channel.
The 800VA toroidal 2X24V is also moans a little nothing ...
There must be something to eliminate this buzz, I think to be making the connections that the NP used in F5 ...

here we go again .......
is buzz there ( it is always around , but not that buzz ) even with nothing connected to inputs ?
Without inputs connected, I hear very light (passes the test), I really have to touch the ear to the column.
Input connect only on the left side of the column is silent, but the other is with a slight buzz. Input connect only the right side the same thing happens.
When I connect the two inputs hear the buzz in the room, all this with zero potentiometer pre course.
Much has been said here of buzz, but I think every case is a new case, so thank you for your help.
put fat and short(est you can manage) wire between two central grounds of two main pcbs
that will look as bridge between them

This scheme reads:
A cable Qed mesh connected between IN and pcb channel. The mesh connects to GND.
The GND Speaker Out connects to GND PCB Canal.
The GND of the PCB connects to PSU.
