will the amp be used for :
1. Elec. Guitar?
2. Home Cinema?
3. HI-FI?
4. full range PA/Sound renforcement?
5. Hearing aid:p
6. cooking food on (in wich case go for a big ZEN)

Actually scrub the last two points

I'd like to build a solid-state power amp, 200+ watts for a full range P.A. system. If you could recommend me to a site or a project, please do. I'll appreciate it very much. How much do you think this would cost?

Well, 2000watts is rather excessive and only in extreme cases do you need this (if it has to be louder, higher efficiency speakers would be a better way to go). But 200+ is alot more reasonable.

There are numerous designs around in that wattage range, just search around a bit on the net. If it's your first time it'd probably be easier to run two smaller powered amps in bridge mode, instead of one larger amp.

As for price well, it all depends on what quality components you use, it gets really expensive when you use "audiophile" grade components, tantalum resistors, polystyrene caps, but can be very reasonable if you use high quality "normal" parts...

allright, thanks. what should i look for on the net, and where could i buy the parts for making it?? i'm totally new to this, but have built electronic things before. please excuse my stupid questions!

Well a simple search like "DIY 200W solid state amplifier" at will give you several results. As for parts I use digikey (, they don't have the more exotic components, but you shouldn't need to go to such lengths first time.

I'm working on a SS guitar amp also. I think you do not want especially low distortion. In fact 0 feedback with a soft clip....
