Unhappy Looking for 300-500W amplifier

Hi!

I need schematics and pcb's for a 300-500W amplifier.
I've some, but they are very difficult and expensive.

There are any with few components?
It's only to feed my subwoofer!

Thx!

Pedro Martins

what about this one?

Kilowatt, a nice 500W schematic for you!

I don't know what you call difficult, but believeme: this would be the minimum you need for such an amplifier. I think you won't find any cheap AND good designs.

HB.

Default Randy Slone's "High Power Audio Amps"

Has several amps in this category. You can order it on Amazon and they ship internationally. This is a nicely written book which builds up the theory and practice of amplifiers.

I believe that Slone sells boards and parts for his amps.

Of course, if you need the Lateral MOSFETs you can always email me.

Or buy one. Way cheaper than building one.
