I have, and it's possible.

P.S. That's all I have to say about it right now. You may want to check out the most recent issue of Linear Audio for an article about the PASS-SIT-1 used under similar conditions.

But if there was an SIT1 used this wont help me. The sony 2SK82 is different.
I know that its possible to use it in this way but the main question is how?
Its also obvious that you need an output transformer. In my opinion whit primary impedance from 150-300 ohms.

P.S. You could send me only this article if you have this issue (volume 4) and I can pay you for just that, I dont need the whole book.

Linear Audio is not my magazine, and I didn't write the article.

You can buy issues here: www.linearaudio.net

So I see.
But could you not tell us more about your experince in this area of curves?
Did you use an output transformer ?

Thanks.

My experience is that there are some nice curves to look at.

Zen Mod gave you a link to the curves you're looking for, and I gave you a reference to an article that explains how to design a transformer-coupled SIT amp. Additionally, you may wish to read through one of the classic tube references, such as The Radiotron Designer's Handbook. Everything you need to is there.

Short of designing one, building it, writing a step-by-step article, and posting a schematic, I'm not sure what more we can do.

Also there is http://www.firstwatt.com/pdf/art_sit_nemesis.pdf if you haven't seen that one yet.

something i don't understand here , if we make a Sit amp is to have a 'tube sound' without the weaknesss to use an output transformer ( limited bandwitch and distortions , and expensive price for a good one)..

Think more in terms of wine tasting.
