Thanks Mile,
So a single MUR860G will just be enough for the h900 circuit, right?
by the way,
Just added you in my facebook acct.
Will post some Apexaudio photos once I finish building some of your featured projects.
Keep up the good work dude...

Hi Apex,
How about a LDR and a LED encapsulated in a dark small tube facing each other to form a modified NSL32, will that work fine for the limiter circuit? Any suggestion instead?
How about the MOCxxx series?
My friend have hard time looking for this opto coupler NSL32 in the Philippines.
Thanks & Regards,

@ Apex,
How about the diode below to replace BAV21?
1N4937 1A 600V Fast Recovery Diode (DO-41 Glass)

Recovery time of 1N4937 is 200ns, and BAV21 have 50ns, MUR120 have 50ns and you can find lots of similar fast recovery diode.

Optocoupler with resistor output can be used for limiter, and you can made some with led diode and optoresistor,

There is no H900 with double step driver, use circuit from this amp,

Sorry, there is no pcb of this amplifier for share, but I think designing pcb is no problem for people who want to build 2500W amp.

greetings how many watts is this circuit can you tell me answer of this
question for general knowledge
1 10 pairs of 2sc5200 2sa1943 at 70 0 70 volt dc how much rms output power will be
produced emitter resistance .22 5 watt
thanking you

With 70-0-70V DC you can get about 130Vpp or 46v rms, output power will be 530W on 4R load,

apex,
does a14
b250
b500
h750
h900
h1200
h2400
use same voltage amflification stage?
VERTEX use OP for DC servo, I want simetrycal input stage like in my MOSFET Amplifier with IRFP240/IRFP9240,

hi apexaudio
greetings is the 2500 watt circuit for diy understood no pcb for
this project can 2sc5200 be used in output stage for same power reason i ask
in my city for one pair ofmjl4281 we can buy 7 pairs of 2sc5200
1 is it 2step or 3 step voltage supply for 2500 watt circuit
2 you told me with 50 100 150 50 100 150 supply it is possible to get 2500
watts from 10 pairs of 2sc5200 3 step hclass
any schematic for diyers no pcb no problem can make pcb with hand
thanking you
