Nice work, I sugest to rotate modules 180deg (heatsinks near transformers.
Regards

Yes sir.. i'll do it...
thanks.

 

[rizqi]

That is good suggestion-even the tunnel would be better formed so more air would go through heatsink(s)!

It looks great are those 10 000uF or 100 000uF capacitors?

Thats 10000 uf 100v (sprague from usa).. 🙂

i have noticed that too,but it will be on 40Vac so it will be at about 56Vdc so it is not critical-it will be all right! nice "jars"! 🙂

Happy new year to you all 🙂

I'm wondering if the Apex Step Driver will work with my Panson Audio Initial Series 4 Pair Output board...

If i understand right my reference point will be fed from the pre-drivers. Is this correct??

Power would be fed by 2x 800VA Toroids ( 80VCT, 60VCT, 36VCT and 24VCT )
The 80V and 60V sections would be fed into its respective my rectifying board, that are loaded with 6x 15000uF caps and the other sections would be a simple 5A or 10A bridge and 1000uF cap.

This is will be applied for each Monoblock...

rohmad fauzy is my good friend,
he build toroidal transformer almoust 40kg
use voltage for apex h900tef 120vac-60vac-ct-60vac-120vac or 170vdc-85vdc-ct-85vdc-170vdc
and 12 pair c5200/a1943
with my design pcb h900tef
