Anyone please info about PCB layout H900 Below, if this pcb lay out corect i will etcing the PCB.
Thak You
Hi all
I introduce you another version of a switching Rail H class from 900W H class amplifier.................I found this diagram on a Russian forum, VEGALAB , I hope you enjoy !
This schematic does not use expensive , obsolete or rare components, and will not pose problems when designing PCB

it" my transformer for apex h900 part II
transformer for apex h900 part III
An externally hosted image should be here but it was not working when we last tested it.

The scheme of step with the TL072 and the other with the IR2117 can be adapted to other amps?
And because a class H amplifier output transistors is less than a class AB for the same power?
is because the potential difference between the emitter and collector is not so high, reducing the dissipation? just a guess...

this transformer u winded or bought?
what is the ferrite size?
what is the wire gauges u used and how many turns for primary and secondary? how much cost for one transformer ?
Nice transformer ......it looks good
but its a lot of cost for class H, 4 rails..no thanks
normally same output power with DIY Class D is cheaper, smaller, less heat

I created this travo own
I use a silicon steel / crgo as its core
imported from japan
10cm high
3.8 cm thick
7.5 cm diameter circle in
cores weighing 9.5 k
primary wire 1.5 mm
secondary wire 1.8 mm
with turn ratio of 1.5
spent approximately USD 1,000,000 (U.S. $ 90)
and need the time at least for 3 days to finish 1 unit travo
Sorry my english
i think not BA159
Maximum reverse recovery time
500ns

Semiconductor: BA159 (BA 159) - SILICON DIODE / 1000V / 0.4A...
i think it is ok but not sure,,,, any comments pls,,,
