Another free ad?

How could possibly be that a tube circuit using a RF transformer becomes OTL?

IMHO the referred amplifier belongs to a new class of his own (after A, A/B, C and all other conceivable variants), but it is certainly not OTL.

    Fear this? Ralph you need help...geting people in to big money highend.
    - no, it was something else. - Ralph 11:32:37 02/16/12 (2)
      bgh offered an insult to 6AS7_6SN7. It was personal and uncalled for.
      As far as the amp goes I've got no worries about that. I just don't see why a person can't be civil.

        "bgh offered an insult to 6AS7_6SN7"
        
        Yet you seem to have missed the insult he delivered to me ... "Another free ad?"
        
        (Mind you I'm being generous, after all you piped in with a "Yup!")
        
        I any case I take the insinuation that I am posting a free Ad as an insult ... YMMV
        
        (as for having the moderator remove I've no problem with that ... for that matter I have no further interest in this forum)

        Not concerned much with the 'free ad' thing- I don't see it that way anyway. But the post seems like it should have been over in the 'Amps/Preamps' forum to begin with- that is why it drew a comment from 6AS7_6SN7.

      6AS7_6SN7 did, and you then chose to insult him.
      
      I have no problem with debate and different opinions, but I do have a problem with people that lack manners.

  Ok man, I love your amp, best I ever heard (the preamp stinks however) but for you to make that comment ... come on! This the Atma-Sphere forum after all.

    Lew makes a good point as does 6AS7_6AS7. The Berning, while being a brilliant design, is also not an OTL. An OTL will not have semiconductors and a transformer (whether air core or iron core) in its output, in fact an OTL will not have any impedance matching devices other than the power tubes themselves. The Berning amps fail on all three counts. That does not take away from the amp itself though. Its just that it is simply incorrect to classify it as an OTL.
    
    Berning admitted in a letter to Positive Feedback nearly 15 years ago that his design is not an OTL. His approach allows for Zero Hysteresis in the output transformer (hence the 'ZH' aspect of his model numbers). However he pointed out in his letter that it was difficult to explain the idea of zero hysteresis, but he found that people understood the idea of OTL, so he went with that. Fifteen years of marketing and arguing later, this fact has not changed.
    
    I would challenge you on the preamp comment though: "Oh, no! Don't take me. Wait a little 'till the big Billy Goat Gruff comes. He's much bigger."

    Ok for you to say the Atma-sphere preamp "stinks" categorically but not ok for Ralph to say "yup" in response to a post made by a 3rd person who has no conflict of interest either way.
    
    Why would it make you so angry for someone to say simply that he does not think the Berning amp is a true OTL? That argument has been going on for 10 years, and it has no bearing on whether or not the Berning amps sound good, which they do. Oh, and you are, to put it in a genteel way, incorrect as to your opinion of the Atma-sphere preamp. (You are aware that there are two different models, I presume. Do you hate them both?)
