placeni da napisu a ne kazu

sp300b just ended conversation over the phone with mehe'll obviously (restless spirit ! ) try lowering source resistor of lower SS .....anyway - what he tried - now we have dilemma what's more influental in his test - change in overall (sum) value of these two resistors in middle of totem pole , or change in their ratiogenerg ( and all ) - be careful when decreasing voltage for optocoupler ( led part) - you can shut off that LED , and circ will be still biased fine , but you will loose current tracking , for which optocoupler is put there , in first place

samo ti radi sve dok uzivas u pravljenju - nista nije uzalud ni najludja ideja koja propadne , a kamoli projekat koji je ipak dokazan

nope ;feel free to experiment with ratio of these resistors ...... meaning ratio of lower vs. uppertake care to re-check both bias and offset after changeeverything is OK , as long you have overall sum of 1R - and at least 1A5 across them - optocoupler is functional

Genije - ako kupis drugi trafo - sky is the limits ovim koji sad imas ostaje ti da ranis svinje i ne diras nistadaklem - odluci se kojim ces putem - ili da ti ja crtam sve , pa da ti onda kupis trafo ........ ili da se drzimo ovoga sto vec imas ?ako ostaje ovaj koji imas - onda vazi sema koju sam postovao - i nemas nimalo naponskog lufta za bilo kakav regNB - potreba za regom je smanjena zato sto imas CCS kao radnni otpor u gain stageprethodno pitanje zanemarujem ; postoji razlog zasto je tamo stavljen P kanalni mosfet u CCS

:air_kiss:idi spavaj

sretno ti bilo sa windows mountom

matter of nomenclatureI'm taking it as - biasing goes from input LTP ......... other setting is chasing offset

neki od virtual drive programaja obicno imam instaliran alcohol 120mount image , pa onda radi sta hoces

BIAS SCHMIAS:you should decrease value of R35 to reduce bias ( if R12 is already on minimal )then - if you are having positive offset and you can't decrease it - decrease R26 ( if R25 is already on minimum)easy peasy , isn't it .....

you can try to change ratio of these resistors between lower and upper SS outputsnow they're 0R5 and 0R5increase upper/decrease lower (in same amount) - more local degeneration of upper SS - comparing to output node - where is - important - tied feedback netincrease lower/decrease upper (in same amount) - less local degenaration .......dunno what results - sound wise - can be ......

@sp300b: why should that be possible ? it is , but I can't see why - put either power resistor from output to negative PSU leg , or CCS that way - with introducing additional current path - you can diss-balance currents through output pair

nedostaje mi bar jos 130V anodnog napona - da bi imao i DC spregu izmedju gain stage i folovera , i da bi bilo sve sa 12BH7jednostavno - njene k-ke zahtevaju naponaaaaaaaaaa

seems that your thinking apparatus is these dayz in ZM mode :rofl:we must include path where we can direct 900mA of differencebut - not in speaker , please :rofl:so - this isn't modern Pass SUSY amp , with introduced additional SE bias

you have diff input stage to servo thatno difference in thatjust one thing - I'm pretty satisfied with Babelfish J2 as is now ........ just need to make it in box , one day .....

aha .....

nope - he meant changing value(s) of middle resistors in output stagewe have 2x0R5 in series ......changing them - you are changing modulation of upper half of totem poleit is impossible to have unequal currents through output vertical . except if you make another path for equalizing currents in that pole

ostatak sema je drndolja ispravljac , filter , par otpornika , kond , darlington , par otpornika , kond

tnx to Sipi - editovao sam vel'ku semu - imao sam duplo vise LED-ovki nego sto trebamislim na 10V ( sto je 5x1V93) a nacrtam 10 komata

take money and run type

onda OK ........... 1. ne moze da skodi - manje ringing-a oko ivica2. genralno neces primetiti razliku u toj klasi drivera3.da - razlog isti kao pod 14. cena , lakoca nabavke5. moze biti samo bolje , jer povecavas stepen ukrucenosti stranica

jos treba da ti nacrtam ispravljac za HT ,kao i biasovanje grejanjate timer za kasnije paljenje Quad-ovog trafoa

Vlado - sp300b is interested ( and I'm asking just because he's busy all day long ) - can you make direct comparison of sound of FW J2 and your Babelfish J2 , considering all differences - you heard FW at Papa's , while you are listening yours at your place ..... we already have Tea Bag's opinion - " The BJ-2 sounds a lot like I remember the FW J2 sounding like at Burning Amp 2009 " tnx

zato doslo vreme za nakurnjake to mu dodje kao snake skin buzir
