450W@8 Ohms Mosfet amp schematics needed

ZuMbAiU · 2nd January 2006, 03:59 PM

Hi everybody.I try to find any schematics of the A.H. AV800 but i cant.
I can`t buy his kit because i am from Bulgaria and can`t use the shipping.
I want make any DIY project with MOSFET`s.I have two 450W @8Ohms

Drivers for this,but i can`t find any good schematics.
The AV800 is good may be for me but if i can`t find the schematics,this project is only a dream for me.
Srrr for the bad english

Dear ZuMbAiU,

450W/8ohm means about +100V/-100V rails!
I think its better to bridge 200-250W/4ohm amps.

Regards,

Thank`s

You are the guy may be for this category,but I have one very big question :
If I have big Drivers AV800 is for me?

Hi, i can't answer you the question if you need that much power... Having drivers rated at 450watts (i guess you mean speakers ?) does not mean you must attach an amp with 450watts to it.
Is this your first amp project ? If yes, i suggest to start with an amp not using lethal voltages...
Is this amp for homeuse ? Or for an SPL-contest ?

You could check www.ampslab.com for pcb's or for inspiration.

Hypex is also an alternative, 400 or 700 W from a small cute unit.
