Upupa, are they your photos? As opposed to photos that he has taken of your amp? And to which post are you referring (there's lots of photos in this thread)?

PMA, what people do elsewhere is not our concern. Please do not drag disputes from other forums over here. You've been warned REPEATEDLY about that.

I don't see any photos at those links. Unfortunately, I do not read or understand Czech (other than a few selected curses), so can't follow where in the thread you're talking about. And where in the threads at diyAudio you claim your pictures are being posted. If you can at least do the latter, that would be helpful.

Pavel, SY is not logged at hifi.slovanet.sk and therefore can not see any attachements, only text. This is a new feature in this forum that Troton made to Federmann and other trolls can not steal images.

Now I ask participants to stop the trip out of thread and returned to the original thread.

Thank you very much.

Godfrey - I share your sentiments. It's not the VAS that's unique, just the form of cascoding (which allows for use of a slower, more robust VAS). I think this is called the "wilson cascode" or something of that nature but really it's just a 2-transistor CCS except with the device-under-cascode replaced with the resistor. It is very effective, if you ever want to give a transistor a low cascode voltage (say .3V Vcb) without the transistor saturating, since the cascode voltage is very controlled. Although my implementation wasn't that great, I'm choking the transistor with about 0 Vcb. It was one of my older designs.

I'm not sure what you mean by cross-currents, but maybe you guessed that I have no way of controlling the VAS (Q16 and Q14) bias current, which may skyrocket or plummet with temperature.

Upa, do you really hate Federman so much, over some silly pictures!? You've been cycerstalking him here, taking every chance to slip some derisive comment. Creepy!!
