Using .029 thick steel will not be good. What lamination thickness do 
you recommend?

I know, but what is Strewth? Is that a foreign language? Or maybe you 
are off you medications again.

Great! Suggest a core manufacturer and part number. Also suggest number 
of turns and wire size. That would prove you know what you're talking about.

>> I am building a solid state audiophile amp that most closely emulates the sound of tubes, but much better quality. Class D is out of the picture. I know what class D is and what it can do but it does not give me the sound I want. These things are going to go for two grand, and will be an all original design by me. I got the rest of it pretty much figured out but I lack the experise in transformers.

** Really ?

Posting ridiculous lies and bullshit about an identified poster are not alternatives to having a counter argument. 

Unless you simply have no brain.

  Wot a brainless piece of human garbage.

** Explain how million of high quality audio output trannys use regular steel laminations. I will not hold my breath waiting. 

  My point about SMPS has gone way over your head.

** A common exclamation of disbelief. 

 Is that a foreign language?

** Maybe pommy slang, but widely used elsewhere.

   Your ignorance of the whole topic is appalling. 

   As are your fucking horrible manners.

 I cared 50 years ago, and designed award-winning
 amplifiers, owned the big woofers, etc., but lost
 my golden ear decades ago.  So yes, now I'm happy
 with a class-D amp and a cheap speaker.  However,
 I designed a 100Vpp 10App DC-10MHz 1000V/us slew-
 rate laboratory power amplifier (AMP-70A, reported
 in these pages).  The design has intrinsically low
 distortion, but with its wide bandwidth, also has
 a high loop gain at audio frequnecies.  A group in
 Germany made a few from my design documents, meant
 for audio use, and reported 2ppm distortion at full
 power at 20kHz.  While I may not care a hoot about
 audio, I can still create superior "audio" designs.

 Also, while we're talking, I am not an academic,
 no sir, thank you.  I'm a hard-working slob of an
 engineer who happens to have worked at Harvard for
 many many decades, and co-authored books.  I run
 an E.E. Lab, and crank out off-the-wall designs.

Seriously, yours was one of the nuttiest post I have ever seen on this NG. 
  
Plus you still seem to have NO clue why it was so ridiculous.
