Why no threads on OTL amps?

Well, this "type" has had the Tenor's for nearly a year now without a single problem, I looked right at them and don't "banks" of tubes ( AR REF 300 MKII's come to mind ), and the heat thrown from them is actually less than many other amps I've had, tube or ss. My audio life is quite active (can't say that about other aspects of my life :), the Tenors handle anything I've thrown at em, "look" cool, are as efficient as I need, and although not a physical lightweight, a definite sonic heavyweight. I'm proud they're working great this week ( and all prior) and excited because I'm pretty certain I'll be listening next week and not wasting time wondering if they'll be working. Oh yeah, they also have all the advantages of an OTL. But most importantly, to me, they sound better than any other amp I've had in my system, mystique notwithstanding.

I like all OTL's and many other amps as well. It just seems to me that as soon as something was said about Berning vs. other OTL's, the fur really flew. Very interesting. Seems to be a very sensitive issue. I hope everyone is enjoying their amps, and I think it is very informative that readers hear the different sides of this issue. I doubt that anyone on either side will be swayed by this discussion, but the process gives opportunity for each to re-think, re-evaluate, and better understand their positions. And good heated discussion is great to "hone" your argument. I am enjoying this thread immensely!

Very good points from all.

However, there are dozens of ZH-270 owners that have had trouble free operation for over 5 years.
With an expected output tube life of 20 years, it's safe to say that one can also expect the same in trouble free years from this unit.

I don't know whether I should post this or not, but here goes....

I read some comments by David Berning himself once about whether his amp is an OTL. I know, I should have the web address for this, but I can't find it right now. I will look for it. It was either on an old thread (2 years ago?) on Audio Asylum, or on a webpage by Gizmo Rosenberg (not sure of spelling). If I remember right, Berning preferred the term ZH (zero hysterisis) over OTL because of issues like those that have arisen here. I have seen Berning amps referred to as ZOTL's. Again, if I remember right, that phrase was coined by Rosenberg. Now, this was a while ago that I read this, so my memory may be faulty (gets worse every year, sometimes every day I think). When I find the address, I'll post it if anyone's interested. But really, like I said before, call it what you will--the issue is PERFORMANCE. When I get my tax refund, I'm planning on buying a used Joule Electra and having a shootout.

those comments were in Positive Feedback in the letter's section a few years back.....he and Gizmo were going at it good as i recall.....i have the issue....will dig it out later.
