Hello there. Yes as stated in the topic i need some advice on the fuzes for my DIY amplifier.
I have 4 toroids in the same chassis Two 500VA 24v and two 250VA 19v
.
Each toroid will have 144,000 UF And the Class A boards will pull a constant of 2.5A on the 500Va toroids and 2A on the 250Va toroids.
So a total of 576.000uf There is a 2000W soft start module on the 220v line
.
Now with the detail delivered my question is what fuze do i use. One for the 220v line for 10a? or do i fuze each toroid and if so.. what fuzes would you reccomend?
I figured id just use 4A input fuze on each 500va toroid and 2a on the 250va. So if one toroid is failing it wout take 10A of power draw to break the main fuze.
.
What shuld i do?

With a soft start I would start with a 3.15A slow blow on the 500VA's and a 2.5A, also slow blow, on the 250VA's.
You could increase them a bit if it turns out they blow 'without a reason'.
