Not too many 200 watt tube amps other there. This one is a time tested design. Know of any other 100+ watt tube amps using kt88/6550?

Instead of using a tube amp to provide 200W, I think it will be way better to use speakers with high efficiency, let's say more than 96dB @ 1m.

Theres plenty of MI stuff that does both...

Since the subject of SPL was introduced, here's an SPL calculator that will help determine audio levels using room size, seating location, watts available, speaker sensitivity, etc.

Tinnitus is very real problem if over exposure occurs.
