just for testing i'm using 42v dc.
It's over 100W at 4R load with +/-42V DC.
Ok Thanksmy caps 0,47uF and 0,22uF with no brand, i think from china.
Regards
Alright sir ,i will down the voltage for the test. To get 400 watts at 4 ohms, what is needed? how many volts and how many watts transformer should I give this amplifier?
Regards.
I want to supplied my amp about 2*40v.
So with 2*30v transfo it's ok (30*1.414=42.5v)(42.5-2.4=40v) 2.4 is the loss in the diode bridge.
But I have a problem to select the power of the transfo !
I think 200W it's ok because the amp can "give" 100W+ the heat loss (30w)+the loss in transfo(40w)=170w (30w of margin).
What do you think ?

I seen the d500 but its too complex i want something like d200 but 500-700w
The D200 was designing for 200W, if you want 500W you must remake all the design.
And 500W is a very high power, it must have many security control.
The D500 is not so complex in front of D200 and it was design for 500W !
I think that coil come from Behringer.why twist the coil so little? it's not a T106-2...
Regards.
You have no expirience in meaking amplifiers, I suggest you to build D200 as your first amplifier and if work...
Regards

It's ferite core with gap from Behringer class D amplifier. Many ferite cores with gap can be use instead T106-2 but with 15-20 turns for 30uH.

Thank You for the explanition sir, i will try using ferite with gap next day.
Regards.
