Yep, the Westinghouse 7591/7868 tube is one of the best sounding output tubes ever made. I have a Scott 299D and a Fisher X-202-B that uses the 7591 outs. Somewhere, I have an X-100-C which uses the 7868. Even though the 7868 is now back in production, it's really crazy priced. Best plan for that would be to rewire for the 7591A.

If you want to build for fun think about using odd ball tubes that
can be MUCH cheaper. See the prices of 7591a, 6CA7, 6L6 etc.

True, those tubes are a bit pricey, but the fact that they are still in production and likely will be forever is a good thing as well.

Dont worry about brute wattage. With good SPKRS 5-10 watts / channel give room filling sound.

Yep. There are some excellent vintage speakers from the 60s that just sound wonderful and are ridiculously efficient. My dad had a pair of ported 3-way 15" Universities that were astounding. I'd love to have a pair today.
My biggest tube amps are my pair of Fisher X1000s which use the EL34s. Right now, I'm running 6CA7 big bottle Russian tubes, but I also have a couple of sleeves of NOS 8417s that I can use.
The X1000 is a beast, but I'm running it through some Legacy Classics tower speakers which are a bit of a current hog. At anything up to and including 60% in a large room, it's a nice combination when I tap them on the 4 ohm lugs. I have a pair of mono SS amps that are very compact, and I've been thinking about using one attached to each speaker and bi-amp them leaving the Fisher to run the mid range and up.

EDIT: I found the Universities my dad had. They were 12", not 15" (I was smaller then so they looked bigger). These had amazing sound.
