ampli MOSFET 360 W

i need help with the part list from anyone having it.

The guy who designed it has left his email on the web page .. you can also by a project book from him im sure the component values will be in the book

P1 indicates that this amp uses Lateral mosFETs in the output stage.
It will cost a lot to build a replica.

@Madtecchy, that am aware of but i tried to ask for the part list without the pcb but i got no response so i thought somebody has the part list for the amplifier.
@ AndrewT, am aware of that sir but i want to give it a try.

Isn't the linked amp a souped up Elektor Crescendo?

Amplifier on that website is a copy - almost identical - the project attached here:

If the builder ever used or tested the 360W capacity, it could only have been for a few minutes in the assembly shown. The design is for 6 pairs of output devices whilst only 4 are illustrated so you are looking at only the 200W version. You will need a lot more amplifier and heatsinking than what you see.

Realistically, the design is not very good, has no protection but is quite basic and could be approximated with the aid of Bob Cordells book without a lot of tuition and the guidance of someone who knows how to design electronic circuits. It will be a far better investment to learn rather than guess and have to ask others for confirmation every step of the way with building a big project amplifier. Think about it.

@Donpetru, thanks for the link but an having problems accessing it because i don't understand the language used. can you upload it for me right here?

@ Ian finch, i get yur advice, never crossed my mind that there was no protection circuit. but can you help me find a mosfet amplifier that has similar specs as the one in the link?

AndrewT · 12th October 2012, 02:16 PM

buy Cordell's book and read Cordells web pages.

All the information to learn how to design a very good mosFET power amplifier is in there.

You can change the display language in the bottom-left of the website. And must be user so you can download files.
