It's a beauty Thimios !!
Thanks all of you!looks pretty good!
It's the first time that i'm close to complete an amplifier using so good parts and i MUST do my best.😎
Just a question.
I'm looking for housekeeping wiring connectors.
Is this a suitable connector ?

It looks like like 2.54mm pitch connector. AWG of wire might be 24. Is suitable for the current it can carry?
Is there a current rating posted?
The thickness/thinness of the section just before the crimp may be quite limiting.

The used contacts typically withstand a maximum of 1A/250V.
Far beyond the needed ratings in the housekeeping circuits.
Have a look at e.g. "reichelt.de" searching for "PSK" crimp contacts.

Thanks i see now,i would prefer the other supplier if it's compatible because reichelt's solution require the crimping tool😉

Yes you need a crimping tool e.g.: search reichelt for "CRIMPZANGE PSK" for less as 20 EUR.
I like to build my own cables exactly with the length I need and the color cables I want. 😉

These toroides is a part of a donation so i don't know the manufacturer.
Thanks for your kind words.
Regards.
Yes,i feel so lucky that i have good friends🙂
Especially now,given a very-very bad economic situation in Greece😡

Better resolvable links / index
The index in post #1 isn't useable if users change the number of posts to display on page:
Press the button "switch editor mode" upper right corner of edit window and directly edit using "vBulletin"-code.
Here an example with link and another example with a bold header line and a list of 1 entry.
The link has variables added: variable "t=" is the database id 307972 of your SA2015 thread and variable "p=" is the database id 5082981 of the post #1 (the link behind the numbered posts 1 - 999 from right side). Between URL and /URL you can add an explanation text which is the link to the post. I edit my first post of every thread in a text file on my local computer in B-code and copy and paste the whole text on update...

Testing the housekeeping(protection)board.
Just to see how this work.
Two lamps instead of the transformers.
3 resistors(1K) in series with the 3 NTC because fault tempreture recognized under normal temperature conditions.
May be different value NTC configuration in software?
Two leds added parallel to relay coils.
DC sense looks good as a multimeter( in diode scale)connected between star gnd and one of sensing pin is enough to recognised as DC fault.
I haven't used a Power switch now,just momentary short Power On pins.
Is this a reason that delay isn't always the same?
The most times is about 25".but sometimes only 5".
Placing the hot soldering iron near the NTC recognized as temperature fault.
Next step will be the communication between housekeeping and PC.

Have you used 2.2k NTC?
The MCU is highly configurable:
- 3 x temperature (+/- 3 degree accuracy with typically available 2-3% NTC)
- DC detection sensibility
- inrush current delay (typically 250ms)
- mute delay (typically 2.5s) - output invert-able
- forced re-powering delay 15 - 30 sec for resistors cooling and children safety
- repower lock on failure
