So here is how this went down.
Someone over there really pissed off Birgir.
Its not nice to piss off the head of the stax mafia.
I mean its REALLY NOT NICE to piss off the don of the stax mafia.
So pictures were acquired.
And reverse engineering proceeded. Starting at about 11am today.
Then by about 4pm the stax mafia had an epiphany.
And so while a slight bit more work is necessary...

Now there is just so much wrong with this thing, i don't know where
to start. OH wait, i do.

So Ray says the A10 is SRPP. Well go and look up the article
written by Broskie... Its SRPP only when the load is resistive
and close to impedance of the cathode resistors. Which by
the way an electrostatic headphone definitely IS NOT.
As usual ray does not have a fucking clue.
Whats more the thing is completely open loop, and i just
finished testing about 50 x 5687's in the output circuit, and guess
what, a variance of about 4+ db. Reminds me of mikhail's
ES1/2 disaster... And the same goes for the input section.
What a piece of work.
But let that not stop Moljinor(sp) audio... Who will be releasing
a board that is both a B52 and a A10 at the same time.
Add much bigger output caps for the dynamic thing, and
put in a switch to lower the output section power supply voltage.
Cheap as hell.
Still the 5687 is being driven way over its cathode to filament specs,
just like mikhail's disaster...
By the way, just the output section of this thing has distortion specs
that rival the Darkstar, >5% at even 200 vpp.
And the power supply... What a clusterfuck. Not even worth the
time to key that one in.
