Well, Valve Amplifiers has only about 600, so you could finish that in an afternoon.

Not if you keep stopping to re-evaluate old designs, make new ones, drink coffee, go off on tangents and web crawls......

Gee, the 3-500z.....sounds familiar! Yep, lots of iron but the tubes would make for a beautiful looking amp!

As you've noted, tubes in this class tend to need very high anode loads, which means that the transformers are even more difficult to make without severe bandwidth restrictions.

All of this is a long way of saying:

1. Don't use SE for high powers.
2. Don't use power tubes that require high impedances.
2. Don't use power tubes that require high impedances.
I wonder which tubes you are referring??
It could be popular tubes as 211, 805 or GM70??
Thanks

RF tubes like the 3-500Z.
