3 step supply
hi apexaudio
greetings please can you tell why all 3 bridge rectifiers have
different current ratings and 4 caps 10000 mfd have 100 volts dc rating
thanking you

LV +/-50V have 25A bridge rectifier and 4x10000uF/63V,
MV +/100V have 35A bridge rectifier and 4x10000uF/100V,
HV +/-150V is series connect MV +/-100V and another +/-50V with 50A bridge rectifier from higher 2x35V AC from 3kW, 6x35V transformer.
hello sir...
can i add 2nd step in h900...??
and then any thing need to chang in digram....??
give some giddiness...
thank u sir....

Hi..Mr. Mile..can I used 3 step driver for H900? If yes..can you help me how to connected those 3 step-up driver to H900.
Pozdrav..
H900 can be use with 3 step class H like in VERTEX but rail voltages 0, +/-40V, +/-80V, +/120V DC is maximum value.

sir if we make another step for h900 with that rail voltage what will be the output wattage?

Thanks Apex...I will try it..

Same power but lower heating.
apex,
beautiful h900
one channel working

waiting mje's
Nice work, is there any case for your amp?

why the transistors lineup incorrectly. no time or don't care.
is that small resistors 1/4watt or-1/2 watt. i think it is half watt.
in my experience first pick correct heatsink . if the heatsink is big measure it and cut it otherwise problem with casing.

apex,
thanks
case already shown post 1213
i want to replace big capacitor the resrvoir
and waiting for mje340
almost complete

WHO ARRRRE YOUUUUU?
APEX THE DESIGNER ALREADY SAID NICE WORK,
HOW COULD YOU SAY LINE UP INCORRECTLY NO TIME OR DONT CARE
YOU ALWAYS COME WITH QUESTION WHAT IS THE DIFFERENCE BETWEEN H900 AND H900V2 AND DONT EVEN SAY THANKS,
NEXT TIME TRY TO SEARCH THE THREAD INSTEAD OF QUESTIONING,WE ALWAYS TRY TO BE POLITE HERE,WATCH YOUR WORDS BUDDY AND SHOW PICTURE OF YOUR OWN WORK INSTEAD😀😀😀😀

mrching,
advantage of class h vs ab
h can kick ab's 8pair or more into h 4pair
and h is less heat
30% at 2 step
and 45 % with 3 step,
h is better than ab by reducing cost of buying more output and heating,spend money in h power supply is better because less heating no stress or less stress at the output.
that is the main reason why we are requesting a 3 step modification of h900,the psu schematic is already given,we just wait for other recommendation,
1 how to apply 3 step

thanks sir mile,
i will finish may h900 project first before i try to make any modification
btw. here's may project im still search for some parts like bav21 so hard to find

i feel very sorry for which i said about your amp.
As apex says same power but less heathello sir..
with 3 step 120-80-40 what is the maximum power of h900.....
thank u .....
