Amplifier For 400 W_rms

[broka]

hey friends. i need make a power amplifier
but for 400 watts in RMS

somebody have a good schematic and pcb design???
i need cuality of circuits. I want to make a good work.I have two speakers, each one of 400 rms of 8 ohms

, the other time it manufactures an amplifier of 200 rms and I burned

if somebody has a design of the PCB and a good outline that please the post, greetings to all thank you

I need quality of circuits.

You could check out Anthony Holton amplifiers.

He makes good amps that are high quality and tested to work alright.
This is why he dare to offer them for public sale.
Without risk of customers and diyaudio people will complain, too much ...
And he knows well how to design for higher powers!
He tells, he has been doing this since 1994, for 12 years.


Most of his amplifiers can be delivered as KITS .... or fully assembled.

Go for quality and some approved design, in the first place.
It will probably save you from troubles from less tested schematics
and some good money, too,
if you need to try something real after investing in several questionable projects first.

or, very good information, excellent, the problem is that I am from santiago - chile, then I have problems with the expenses and costs of shippings. however with a good design in PCB and outline can build the AV800 that is the one that need, greetings friend...

[broka]

looks I have these planes that it is the AV400 according to me, but according to the characteristics that you tell me for a load of 8ohms, I need an AV800, if you can get yourself the planes, serious of a lot of help, I happen to you those of the AV400 that are in the enclosed file, greetings friend

you can download a file in this link:

I downloaded
Protel MOSFET 400 Watt.

It has +70 volt and -70 volt.
Using 4 x IRFP240 + 4 x IRFP9240 MOSFET in Output.

It is same power like Aussieamplifier AV400.
Will be something like 200-225 Watt in 8 Ohm, max. ( If +-60 Volt Peak Output )
And 400 Watt something, in 4 Ohm.
It is a very good schematic!
Good amplifier.

I have also the new NX400 seen
with a very low distorsion....

Yes, that is!

[broka]

thanks for your answer, however , i have the av400 pcb design and schematic,

but i am interestin for the AV800 PCB protel diagram, and schematic...
