I will confess, I do really like the 8B. I rehabbed one for a hifi friend & fellow traveler years back. Nothing fancy -- indeed, I removed some of the esoterica (e.g., the "bumblebee" coupling capacitors) and replaced with good,
cheap modern replacements (Illinois "lemon drops"). Heresy, right?
Maybe -- all I know is the result was, to my
ear a superb amplifier.
I have a Fisher 500. Nice receiver with a great 1960s aesthetic. That one, too, thoughtfully rehabbed (not by me, though). It paired well with the Klipsch Cornies

I still had when I got it -- the defects of the latter were nicely smoothed over by complementary defects in the former.
I like those Scott integrated amplifiers, although I prefer the pp EL84 to the pp 7591 models -- and I'd never put any in the big leagues.
The 8B, though -- I could live with one of those.
The Mac MC-225 is another vintage, store-bought (commercial

) amplifier I could live with.
Both are too expensive, though, at this point.
