Dear Paul,
You hit the nail right on the head. I've felt AND said for years that this
industry in certain regards is taking giant steps backwards. Mostly, it is
because these idiots do not HAVE A CLUE as to what's happening. They
couldn't come up with any new circuit concepts if their lives depended on
it. These single ended nutcases belong in an asylum as far as I'm concerned.
How can anyone in their right mind believe that some or a lot of distortion
is in any way acceptable? This just doesn't make any rational sense.
According to these morons, all the last 40 years of scientific work and
endeavors have been a waste of time. They want us to go back to 1925 which
was even before feedback was discovered. Is there anyone alive today that
could tell us all how "wonderful" things sounded in 1925. Shades of the most
awful speakers and cartridges and electronics known to man. Give me a break.
When I get my web page up shortly, a whole lot of this nonsense is going to
be debunked. Stay tuned.

Dear James,
My apologies. I do not mean to give the impression that I am
prying for a real technical, indepth discussion or any information
that would be proprietary. I am just interested in audio history
and current rage with single-ended-triode amps vs. ultralinear
vs. transistors appears to resemble the early transistor days with
transistors vs. tubes, germanium vs. silicon, etc.
The SET world is just abuzz with terms such as directly heated,
indirctly heated, tetrodes in triode mode, single plate, etc.
I have even seen solid state amps with ONE output device in
single-ended mode costing thousands of dollars!
The point of all of this is I'm just wondering if there is
really progress being made or if it's going back full circle
with people trying to design transistorized products like tube
amps and, perhaps, making the same mistakes.
I'll leave it at that.
Best regards,
Paul Bigelow

Dear Paul,
The problem that I can see here is one of giving away (for me at
least) 40
years worth of acquired knowledge.Why on earth should I tell the
world what
I've learned over the years so they can design products with the
advantage of
free engineering. I've often thought about writing a book on the
subject of
Audio design/ART and Science. However, it still comes back to the
same problem.
After all, my circuit topologies up to the moment have to be the
most copied in
history along with the original Williamson tube amp. There's much
more here
than meets the eye and yes you'd better believe that there are some
secrets to
great analog design. But to be quite frank and honest, I prefer to
keep these
secrets just that.
I know that this is not what you want to "hear" however, I'm not
dead yet and I
will be coming out with new products shortly and I can be very sure
that again
they will copied extentsively.

Dear James,
Thank you for the response. I would certainly agree that a
learning curve was necessary to bring the transisitorized
equipment to a high level of performance but what my inquiry
was about what needed to be learned and what was missed.
Just because these companies were on a learning curve, it
sure didn't stop them from developing and turing out the
equipment.
For example, did the early designers think of transistors
as low voltage tubes and design accordingly, simply "dropping"
the transistor into existing tube designs and eliminating
the ouput transformer (when applicable)?
I'm reminded of the early days of radio. Scads of
regenerative receivers and other exotic designs hit
the market with wildly differing performance until
the superhet quickly became the norm and raised radio
performance to another level.
Best regards,

Dear Paul,
I hate to belabor the point, but would you like to drive a
Model T
Ford
today with its planatary drive and spark advance, etc. I think
not.
The
early years of solid state from the mid 50's through about the
mid
60's was
a long learning curve. During that time the only two guys that
had
their act
together were Bart Locanthi at JBL and of course the great Sid
Smith at
Marantz. All the rest of the so called engineers couldn't
design
their
collective way out of the toilet because they had not yet
learned
how to
think "solid state". The semiconductor manufacturers were also
on a
very
steep learning curve and it wasn't until the mid 70's that we
were
able to
get devices that were really decent.

Dear James,
Most early solid state equipment, as a class,
seems to be viewed with much disdain by current
audiophiles.
If early solid state is as bad as many audiophiles
state, what do you think were the problems with
early solid state and what did the designers miss?
Was it a design problem? Problems with the devices?
Or Both?
Best regards,
Paul Bigelow
