da gi preseces popola - KRELL KSA 50 bi ohladilo - polovina po kanalili maaasan AXza KSA 100 bih vec morao da gledam knjige starostavne , uz dimenzije naravno :sarcastic_hand:vidim ja da ti jos nisi odlucio sta hoces ........

i zakljucana je - do sutra ; mada moze biti i do proleca - niko nece shvatiti da ni muve nije bilo a napravio se slon ZM irelevantni postovi za temu prebaceni ovde : http://www.diyaudio....iew__getnewpost

nije maglaza svaki cilj postoji premaz ; neki dodaju masu , pa je to znacajnoneki toliko malo dodaju masu da nije znacajno ( po pitanju mase )

kol'ko skontah - to ti je veoma prakticno reseno napajanje

postovani kolezielem - ne interesuju me ovi 6L6 +7025 jerbo ce ti svaki Fenderash dati lepe novceako imas spisak ostatka (ove 25L6 i ono sto nema na slikama ) , blagoizvoljevam slanje na PM:hi:

sorry - multitasking :Viannen_loungelizard:iskreno - ima jedno 4 godine kako sam se zamajavao sa SOA , dosao do merodavnog zakljucka da mi za servisi rad ne treba problematika , a za ovo ostalo tek ne - ne razvijam SOA zastite a pristupom se resava eventualni problem u radu - stavis dovoljan broj izlaza i driver stage koji to pokriva 2 puta .....da se obsetim trebalo bi mi vremena , a mozda bih ti jos i prije napravio neku medvedju usluguidem d akuckam mailove ovima sto ne umeju da sastave A5 ni sa mosfet ni sa jfet ulazom .........

ako's drilovati - uzmi aku busilicu - manje struje trosi no ukljucen racunjar:Viannen_loungelizard:

Odavno je i zavrsen i uknjizen ; to sto je sad objavljen tamo nista ne znaci za "projekat" :sarcastic_hand:naravno da uvek moze i bolje i drugacije , ali u onom obliku i nameri kako se jos onomad krenulo - zavrseno

Hvala Kolezi ĐNik:Viannen_loungelizard:

sreca pa mogu i bez rodrigeza i tarantina i bez mit dem winde verwecht

that was just pointing that I don't care and it's not imprtant what you are measuring at Q6 - if you have -11V to -12V at bases of Q2 & Q3 ; in that case LED string and Q6 CCS are serving their functionif channel is working - then they are functional , so you don't need to check them there - voltage check points at schmtc are good enough for purpose

what's important regarding Q6 is just voltage at bases of cascodes - Q2 & Q3 ;they must be in range of minus 11-12V - exact what is voltage drop across leds+1N string

:dubbio:point is that upper jfet is open but lower one isn't , so you are having same offset as in case that you have high value resistor instead lower jfet , while upper one is trying topump current through it .I can't figure how on earth - what's stealing current from R35&R12 combo ; is Q4 OK ?with positive offset on output - it will be logical that Q11&Q12 are sort of choked and that Q9&Q10 are conducting more current , so you should have greater amount of voltage across R35&R12 ........ but not - here is contrarycheck Q4 please

ako je regionalno podesenje stavljeno na serbia , dovoljno je samo promeniti zarez u tacku - kao decimalni znak

have you continuity between R32 (not jfet side but left side on schematic) and C of Q2also - check continuity between R32 and Q14

kolegi svaka cast !

steine - prosledi datoteku Daudio - zaboravi na moj PM - red je stafetno

OKtry to preset - in cold ( prior to powering up ) sum of R12+R35 to ~250Rthen try standard procedure with variac

Tea- let me know ( probably again , so sorry ) - what's Ugs/2A of outputs used in that broken channel ?

:angry27:nisam ja velik moj Fullrange Bro je still veci od mene , kako god okrenes ( i sa koje god strane pogledas )

ma ja sam ti samo matori corava koka zrno ubode , makar i kvarno ......

za decouple stavi sta hoces - bitno da je min. industrijski kvalitet, a sto se tice nfb - nisam bas sasvim siguran sta ce to tumislim - to je varijacija klasicne Hitachi application note seme , a to je radjeno i sa cap-om u nfb i bez njega ;ok - stavlja se da bi amp bio foolproof-niji ....... sto cisto sumnjam da ti je neophodna f-ja

imam kuci set izvucen iz ostataka MIG-aako se setim - mogu da pogledam koje to nisu za jednokratnu upotrebuinace - preamp napravljen sa cevama iz elektronike meteo balona koji je doleteo iz ruskih visina do nizina drevne Backe radi i dan danas

simple said - complementary and cascoded is simply better ;in fifi vocabulary - less sonic signature tech speaking - lower output impedance , works in constant voltage regime off course - choice is all yours
