sta fali tackastom vitru, za to? manja frka no alisanje u srbijicu

jbga, nije Kosher

ma to sve zajedno i to stereo , ne trosi 30mA, i to bez racunanja

stavi semu ovde ako ne znas da odredis struju potrosaca

struja potrosaca?

da napravis Vremeplov?

baci to, sa takvim ostecenjima, to mu dodje ko kineski produzni hladjenje? kad dodjes u situaciju da se elkovi greju, ne radi se o hladjenju, nego se radi o problemu koji treba resavati audiophooleraj, klasicni

KC, nova PL

bice to u svim Jagodinama, oduvek

prakticno svejedno za audio upotrebu

od ovih predstavljenih , SissySIT i B. M25 vec dobro poznati od ranije, revision napravljeni bez zvucnih promena ostale sam cuo prethodno u formi prototipa, neke mono neke stereo ovo sto je sad u toku je prakticno potvrda funkcionalnosti pcbs koje pristizu msm, nije neko iznenadjenje nijedno samo po sebi, bar ne sad ono sto mi je drago, za razliku od pre par godina napravljene Schade iteracije, ovu sam najzad uspeo da uradim bez kompromisa znacajan problem je bio i biasing voltage i pobuda za Schade-d mosfet, biasing zbog nesimetrije napona sa naspramnim mosfetom, a pobuda jer moras cvrsto da ga poguras i zarad stabilnosti transfer k-ke i zarad Freq. odziva ...... ako je pobuda wobbly, krenu da samaraju interelektrodne kapacitivnosti u kombinaciji sa Schade deliteljem u gate-u....... u fazonu rdjavome svaka dlaka smeta

kao sto rekoh, nisam jos ni na pola spiska

ima jos parnekoliko , u fijokci

eh, nismo jos ni na pola spiska

How it sounds ...... will it drive F4? I'm gonna toss all my precious ( 'till today) SITs and VFets to OPLDF bin, cruncher is gonna work these days anyway ..... THD Spectra comparison with SissySIT - go to #7 in https://www.diyaudio.com/forums/pass-labs/371272-sissysit-3-a-post6626308.html

some funny porn, as proof that I changed something when I made those few changes from Babelfish M25 R.2 ( few resistors, TP2640), after flipping power switch - Iq came to same value as it was set for B. M25 all what was needed is to correct DC Offset, for 400mV or so easypeasybreazy

same settings, 4R Load

THD measurements +/-24Vdc rails, Iq 1A5 , 8R Load

name of the game was to create SIT amp for Greedy Boyz Hordes ...... naah, I don't care for Hordes, I have all the fun logical thing would be to put emulated SIT in same position as in DEFiSIT/SissySIT, which is positive rail; from some reasons I tried in simulations to put it down (lower rail), then realized that that approach is resulting in difficulties - choice of small P channel mosfets for Source follower/level shifter, having low threshold Ugs is much smaller than counterparts in N polarity however, me being stubborn as I am, stayed with P channel ....... SF Ugs is important, beacuse it is additive to feed point of Schaded mosfet, which in this case we have as -3V8 (ref to output) , then Ugs of TP2640, so resulting biasing voltage at TP2640 gate is around -5V4, ref to output in same time , Ugs of upper mosfet is +4V42, which means that resistances from rails to adjacent gates are still pretty symmetrical one of interesting things - of all lately seen amps, only this one is having same current distribution of output parts as real DEFiSIT is having - up to clipping point of more active part, parts are working in antiphase , fighting each other..... and only at and after clipping, lesser acting part ( one with lesser xconductance) is helping other one see attached - graph from sim, but confirmed in vivo....... though, easier to post this than capturing scope screen ..... counting on fact that I have a scope from Lee De Forest time, but before triode invention sim shown from output sine of around 20Vpp @ 8R load biggest sine - upper mosfet current smaller sine - current through load smallest sine - Schaded mosfet current

-Honey, I Shrunk the Kids! ...... no, wrong movie..... -Honey, I Shrunk the SITs! .....no, there is no such movie.... -Honey, I created a Monster! .....no, there is no such movie.... -Honey, I am The Monster! ...that's the movie which must exist!

yup, seti se - bez overall NFB

samo me interesuje cemu magicne nogice i silno klampovanje baterijama ..... da neutralise to sto je smesten na zvoneci plek od milimetra ........ garant
