My, now isn't that Special!

They also have Direct Reactance Drive
for an SET amp at http://www.welbornelabs.com/drd.htm

Dirty Real Drivel?, or what?

All sorts of claims, and no proof for its validity,
Aye, that's the Web for ya.

The blokes in the audio club down here read all the silken tongue
clap trap about "the sound", and then start thinking it just has to be
better
than anything else, and because price is low, are tempted to buy it.
But when I see the schematic, I start thinking of 101 ways
which could be better.
But what is important is the information which is missing about the amp,

and its parts.
I have no doubt it works OK, and probably sounds well,
but it ain't hard to get a good sound from a 300B, and you don't need a
550v PS.
And with no loop FB, surely the brand of 300B is important......
