Power is not most important for amplifier, good working amp is better than unstable amp with distortion.
my mom and dad keep telling me exactly that
power is nothing when its not well caged
but i want high power anyways
For anywhere,il turn it down when im in my home but when i go on a vacantion outside i crank it up
boring,i aleardy have 2x40w amp and its boring,it dosent make my speakers move at all
Sir Mile,
Will you pls. share the bottom copper artwork for etching on D200 rev.2, I have wanted to build this amp, I have the parts for it.
Thank You

Ok i will go with d200.2 with irfb4229 at 90v for 500w at 4 ohms,will it work with 2 ohms with these but its not very necessary to work at 2 ohms
Thank you sir mile, I will be posting my build soon...
A few clarifications;
D200 to D200v2
BD241C = IRF640(?)
BAT85 = 1N4148
12vz = 15vz
Is this correct?
Regards!

Yes, if you get +/-75V (150V peak to peak) without cliping on amplifier output.

I suggest you to use IRFB4332 with +/-90V at 4 ohms load and test D200 at full power, also with 2 ohms load, and after test please share your exspirience in this thread.
Regards
i dont have testing things like multimeter or ociloscope ,i only have computer,soldering iron and only speakers that cant handle more than 50w and no dummy loads.If you say it wont blow up with 4332 and 90v,i will slowly buy the parts and assemble them,but i also need to find a smpsu schematic and pcb without special or expensive parts
Im more than happy to share the results after i build it
A basic rule of thumb for class d is that if you don't have an oscilloscope, do NOT build a class d amp!! Especially not one that exceed a few watts of power.
To build a class D amp, a Oscope is a must!! It's a requirement!! Without it you cannot verify the amp is working properly and doing what its supposed to do.
You need to be able to verify that it is switching properly without excessive ringing (caused by excess stray inductance) and not just oscillating wildly all over the place.
