A bright student would not have allowed Stew to trap him into accepting that nfb around Stew's bjt is allowable because of your stupid persistence with your internal triode nfb theory. Talk about reductio ad absurdum! You didn't even have the sense to wonder if the bjt already has its own mysterious internal feedback mumbo jumbo. That would have at least maintained the appearance of honesty. Now you have allowed him to squirm out of the whole project. Maybe Stew is cleverer than we thought... I have no intention of 'squirming' out of anything. OTOH, Patrick does not dictate anything to me, and when I have a decent 'KISASS' design assembled and tested, it will be a minimum parts count design, with unconditional stability and hence suitable for a beginner to construct, putting around 10 watts into a 4 ohm load, and it will use any circuit configuration I damn well please. It will have zero global feedback and an essentially single-ended Class A topology, but otherwise, anything that proves to work well will be used. The timescale will also be of *my* choosing, as I'm much too old and ugly to rise to cheap taunts. -- Stewart Pinkerton | Music is Art - Audio is Engineering |

wrote: "Stewart Pinkerton" wrote Incidentally, your view of the difference between a tetrode and a triode is misleadingly simplistic. The screen does not merely break the "loop", but is an active element in its own right. Once you do something with it, of course it is. Otherwise, merely a screen preventing the gain reduction mechanism from occurring. Save your pomposity for your unfortunate students. -- Me? Pompous? As in "pretentious - moi?" :-) So now we have an imaginary screen defeating imaginary nfb in an imaginary manner. As if adding a screen to a triode isn't doing "something with it". Semantics - the last refuge of the loser................. If to avoid pomposity I should bring myself down to your level, I'd rather stay pompous. I knew you'd say that! Judge Dredd Cute trick to get that nfb round your bjt, though Patrick's proper shot himself in the foot there. His metatarsals are indeed so perforated that sitting in front of a keyboard is his usual pose (pun intended). BTW, I intend no 'cheating', simply using the active devices in their optimum configuration, just as any designer would with the 6SN7/300B. -- Stewart Pinkerton | Music is Art - Audio is Engineering |

That's fine, Pinkie, but at least you could tell us what time you've
set the alarm for . . . |
