The green class A

For the first time in history -
true class A runs with high efficiency

Introducing CSS(tm)
the patented semiconductor class A circuit

True.

Over the years, countless attempts have been
made to design true class A circuits with a
reasonable degree of efficiency. None have
been successful.

Until now.

Crystal Sound System (CSS™) is the name of
a new and patented class A transistor amplifier
circuit which combines the high linearity and
accurate sound of class A with the high efficiency
of class AB. The circuit is ingeniously simple
and brings the sonic performance of audio
amplifiers to a higher level than previously
possible, without sacrificing efficiency or
producing excessive heat in the way that
traditional class A designs do.

Due to it's simplicity, the CSS(tm) patent can be
applied to virtually all applications now using
class AB amplifiers, including everything from
integrated circuits to high power public audio,
with only minor alterations to the original
design. The result is a more linear and accurate
sounding amplifier, which puts less stress on the
power supply and reduces high frequency
interference, while retaining the stability and
high efficiency of the original design.

In every product where audio quality is of concern
and an amplifier is present, CSS(tm) can
dramatically help improving sonic performance
without affecting manufacturing cost.

Here's the rest:

Quote:

The amplifier includes a transistor pair (T1, T2),
whose effective emitter is connected to the output
(OUT) via a resistor (R1) in parallel with a diode
(01). A constant load circuit, consisting of a
second transistor pair (T3, T4), a resistor (R2)
and a bias circuit (T5, R3, R4) is connected between
the negative supply (VEE) and the output (OUT).
The constant load circuit includes a shunt line
between the emitter of the first transistor (T1)
and the base of the second transistor pair(T3, T4).

This shunt line has a bias circuit (T5, R3, R4)
which is adjusted so that the output diode (D1)
will not conduct when the amplifier idles. The
constant load circuit ensures that a current
continually flows through the output resistor (R1).
The current through the first transistor (T1)
will always exceed a lowest value and due to this,
T1 will constantly operate in a delimited, generally
linear part of it's working curve. The first
transistor (T1) can handle both the positive and
the negative polarities on the output. By definition,
the amplifier is therefore a class A design.

I didn't try to send e-mail

I'm usually leery of unsolicited info that comes in the mail.

When it comes to hard copy spam and spam, I'm a skeptical cynic. Except on even numbered weeks. Those weeks I'm a cynical skeptic. It really doesn't matter a whole lot if I lose track of which week is what.

Do you think this has good potential ? Or is it more likely file 13 stuff? When it comes to circuits I'm still learning my ABC's -

Uh Oh looks like you're out of a job. I bet you wish you had thought of this. Who knew it was that easy
we will miss you

But what the hell:

I haven't read Nelson's patent on the Aleph current source, but boy, this looks dangerously close to an improperlyn granted patent, or downright infringement.

So is this a joke, or what? Who would be silly enough to send such an advertisement to the man who owns what may very well be a prior patent on the same thing?

I'm baffled! If this thing is real , I'll bet they'll be in for a little surprise when Nelson (or perhaps Nelson's lawyer?) phones up with a polite "excuse me, but..."

The fly in the ointment is that defending a patent can be a major PITA, actually, an expensive PITA... Nelson seems admirably calm... I'd be right pissed if it were my patent! But I guess this isn't the first time NPs had to defend his IP... the price of being an innovator (unless, of course, your Bill Gates, in which case you don't actually have to innovate, nor defend yourself from competitors you can just buy or strongarm into bankrupcy, depending on how you feel that day! hehe).

LOL! Jocko, you fiend! Still steaming over the recently dredged-up issue of CE certification, are we?

OMG this forum's been entertaining lately...
