What does this circuit diagram of 1000w ways to use how many transistors?

Sanken 8 to 16 pieces of transistors and is it http://www.afiata.com/1000w-2000w-power-amp-ocl-circuit-using-sanken/ correct circuit to drive a woofer and the number of transistors and what to use.

It is incomplete. Certainly, you need more than shown in the diagram to run 1000 watts from a single pair 2sa1494/2sc3858 is good for 200 watts as a "maximum absolute "rating (the sheets). But you can not solve this problem simply by hanging a group of them in parallel. You must be very careful to match, and even after that, you have to do extra work to avoid oscillation and other questions. In addition, the scheme calls for a + / - 30 volts of power. I guess it's for a car? To provide 1000 watts output at 25 percent efficiency (not uncommon) that the offer should have a current rating of at least 70 amps. A + / - 30 volts, 70 amps supply which operates from 12 volts is not an easy task either. And even after these issues are addressed, there are hidden pitfalls in the construction Audio power amplifier high. I'm sorry, but I would say that an amp of 1000 watts of power is not really a DIY project when construction details offered are so scarce. An experienced handyman audio amp would be able to take the scheme and implement safe and would also supply circuits at hand. If I were you, I would go to certain web sites audio DIY and forums and playback starts. Then build something simple and low power that does not start a fire if a party fails ... as a headphone amplifier. Then, try power amplifier that operates on 12 to 14 volts, no need for negative supply, perhaps from a kit. The kits are a good way to learn construction techniques. You do not learn much about the topology of the circuit construction kit, but someone else running physical concepts through hands shows you things you really need to know about construction techniques. And you do not spend much time collecting parts from various sources, it must also avoid compromise when you can not find the exact parts you want.
