Hi RATs!
The amp design in question has one happy listener. I don't know if he
is a Supreme Sonic Purist or anything - he posts about amps he builds
that he likes 
If any of you have not built a single tube amp, get busy. What you
hear when there is nothing else there will be a wonderful learning
experience SV-83 and 417A each do quite well, alone
If you choose the 417A, to save you time, here is my Type 68bis "MZ"
417A one-tube amp:

Suitable speakers are shown with the photographs referenced above;

The High Wife Acceptance Factor (HWAF) horn:

is authoritative but pricey with Lowthers; ask Mick about Fostex
equivalents. The Impresario, with its guitar driver, is inexpensive
and easy to build and surprisingly articulate for the money:

And for
those of you who need to explain why that is a waste of time, money
and effort in all the very best techno-garble, Merry Christmas!
It could be worse. Imagine what one of those technogobblegabble guys
would taste like as a turkey...
Happy Ears!
