At that power level, you're probably talking monoblocks. Buy six...

Is this a surround system for an amphatheater?

What is your application?

That is a lot of power for tube amps.

I could build you 4 150/200w mono's and 2 60/80w mono's. Tying them all together is up to you.

Do you own a forklift? :D Seriously such a beast would be heavy, expensive and require a pretty good cooling setup. For the price you would pay for that you could build more modest amplifiers and have enough money left to buy or build some speakers that don't require an arc welder for an amplifier to beat them into submission. ;)

The trick is getting a good quality 6 channel preamp. Once you do that a trio of moderate power push pull stereo power amps (6L6 class or KT88 if you want more power) mated with a nice solid state powered subwoofer or two and you should be in great shape.

Keep in mind that those "200wpc" home theater receivers out there are really more like 35-50wpc in real life. As a data point I am testing a KT88 Single Ended amp that I am building for my grand daughter with some Mark Audio CHR-70s (not all that efficient at about 84dB/w/m). The preamp that I am using to test is not even capable of pushing the amp to full output as it has insufficient gain and it gets plenty loud in our living room dining area. If I were getting the full 8 or 10 watts it is capable of I might have to leave the room for sake of my hearing. :) 30 or 40 watts should be plenty with decent speakers especially if you are running under 80Hz signals to the sub as is standard practice.

Get some vintage Altec or Klipsch speakers and the little RH84 SE amps would be plenty.

This is alot for power even for a SS multi-channel amp.
The max you will find on the market is this Ming-Da 5 channels tube amp, looks a good heat for a nice winter, output tubes are KT90.
