da bi isao sa sim programom u sitne detalje, moras imati i znanja i kilometrazu sa istim to je rezervisano za opasne igrace, koji su ispravnost i detaljnost modela potvrdili u praksi dakle, ne zanosi se sa tim ....... ja licno LTSpice koristim kao malo bolju salvetu, lakse za ne izgubiti msm radi sta oces, ali varirati tipove kondenzatora i ocekivati da ti to nesto smisleno predvidi je dupli SciFi

So , some conclusion(s) - 2SK2087 is worthy one in SissySIT cradle, whichever revision is in case Have plans to try it soon in Common Source and Common Drain circuits, both Mu and Choke loaded, very soon; first one should be most likely Warbler, nothing else than choke loaded source follower stage, with all bells and whistles of proper biasing and buffer and yadayada 35Vdc-ish single rail, Iq 3A-ish for Big Tokin, 2A-ish for 2SK2087C 'nuff for today and yes, it seems SissySIT (42) is now official edition (Caliph instead of Caliph, (42) instead of R.3) problem is , I'm feeling as living Groundhog Day ...... whatever I'm doing, it always seems as same amp Iznogood ( Caliph):

Now, battery of tests Will post same measurement of THF51S and 2SK2087C in same post, trying that THF51S is on left side pic; anyway, THF51S related are not having type note, while for 2SK2087C I remembered to include note in caption go figure general trend, already established in thread liniked in first post, small one is having lesser THD levels than big one, all the way to clipping , and small one is having lesser power than big one in all cases - dual rails, 24Vdc-ish, Iq 1A8-ish 1W@8R
