ziva steta sto ne zacnes svoj blog ;pa da pises u momentima svim ...........

call me cautious repair man :Viannen_loungelizard:I had my share of repairs , where someone plug input cables without touching chassis with hot tip before .I drew them from habit , but without intention to really put them on pcb . CCS is CCS ; black box , if you ask me - and putting SSouths in CCS is waste squared ; you can make it even with bjts if you wish . under condition that you make good , not mediocre one .problem was probably in some other area - but now I can't take a look at BA1 schm ..... too much multitasking lately , and I have just one dumbe kopf naah - what I did is just Babelfish-ing Papa's bread crumbs

Zvule - vidi se da nemas pojma o tehnologiji ;drvene ploce su secene laserom , a moraju biti te dimenzije jerbo se drugom duzinom rezanja samozapale

svi su ER i FR takvioni koji nisu - imaju opasno smoothed graph

semu imas par postova nazad

@ Synca mogao je dosad s Beymama ljubavi da se navodi .......

moras da priznas da sam ja otvorena duha po tim pitanjima ......

Lin

naturlich

mislis PRaT ?

onda neka prestonicani pomazu ja nemam znanje lokalne scene

pomaze ako napises u profilu odakle si

ZM knows Bahnhof:buehehe:

upravo tako ........ al' nebitno - bar ako stvarno ne pokusa da ih strpa unutra

ne verujem da je iko pomislio da si ti neko drugi :buehehe:inace - ima nas ovde koji smo svojevremeno kupovali SAM i pravili stogod ..... ajd videcu sutra da li imam u furdi koji od tih cipova

da se nadje - origigi iz SM

Miso - sad gledam pcb ....koliko parova izlaznih mosfeta imas po kanalu ?

verovatno ti je predebela struja kroz ulazni LTP nikad nikad nikad nemoj stavljati trimer u paralelu sa fiksnim otporom - na takvom mestu evo ti prepravljena sema - cilj je da imas 20-25mA kroz ulazni LTP povecaj R7 na 390 , moze i na 420 oma moras imati namontirane izlazne ( bar jedan par ) ako mislis da imas punu funkcionalnost , ukljucujuci offset na izlazu ne treba ti nikakav dummy load na izlazu , ali ulazi moraju biti zakljuceni na gnd

cemu zamena ?treba naci kvar , a onda su sigurno dobri mosfeti sa kojima je projektovan ampdaj koju sliku i dodatnu informaciju

why wasting 2SK170 , when with two-bjt-CCS you have very nice CCS , with superior Tempco . with R9 set 20mA through input LTP ( exactly 9V4 across R3 )both R12 and R25 are influencing Iq and offset ; start with R25 at zero , trim R12 to desired Iq , then fiddle offset with R25 20mA type is good ; they're operating here at 5mA ; nice value , considering both internal resistance , tempco and noiseQ8 ? base of Q8 via R24 and base of Q5 via R2 are connected to neg PSU, via R21 put some little heatsink to Q8 ; Q7 is maybe just warm ; difference between BD140-10 and BD140-16 , same as between 556B and 556C are just in Hfe ; do not even bother ..... tell me more .....

nabavljivost gde sta postopretpostavljam da si vec uradio domaci zadatak .......
