Here, it is a equation of purpose. Are you doing a club?

If so, buying a amp(s) off of ebay might be best.

For personal use ,1 KW is quite a bit of "over kill"
At 2 X150W + a 200 Watt sub amp, my house can't take
any more.

Anthony Holton's kits were all sold commercially, and have all worked well. He is a good designer

I agree with ostripper however, this sort of power with a Class AB amplifier is insane. This is what Class D is for. Also, you are not going to be able to build it cheaper than you can buy it for.

I can do on with av800's pcb layout i think. If i add 2 pairs of IRFP240-9240 o/p devices what must i change? If its hard i can do directly av800 pcb. But if it can be done with some changes i want to do. Thanks for all replies and helping friends.
