upravo taj! služi da se provjeri ima li na izlazu pojačala oscilacija koje su izvan zvučnog opsega (više od 16kHz recimo),dok je ulaz otvoren ili kratko spojen (bez pobude). nije nešto ali bar je nekakva mjera,bolja od ničega. lako se pravi i košta malo,pa što ne imati tako nešto? Smile

Do malocas sam radio-testirao zato je post u kasne sate. THETA je sasvim sklopljena i celo vece testirana u mnogim aspektima a najvise vezano za kontrolni sistem. Ima jos tri-cetiri sitna "baga" koje ce Nebojsa verujem lako srediti a i nisu zbog njega nastali vec mojim previdima pa sam mu dao pogresne instrukcije...
Jos jednom hvala ZIKI-ju za hladnjake.... ove je tesko zagrejati... mada zbog kasnih sati i ukucana nisam mogao da to bas "odsrafim" duze vreme. Posle 4 sata relativno umerene kucne svirke (recimo 20-30W) hladnjaci stignu na 35^C. Stignu oni tu vec posle nekih sat vremena ali se tu i zadrze. Sutra cu probati koji sat na velikoj snazi pa dokle izdrzim.

Sinoc nisam stigao da ista napisem. Pojacalo je drzano dobra dva sata na oko 2x120W prosecno i ne mogu da hladnjake preguram preko 45-47^C!!! Onda je zena sisla u lab "da vidi da li sam normalan jer ne moze da cuje TV a i pod se trese" (SILA je sila!) pa je test okoncan. Nisam ni ja mogao dugo da budem u prostoriji pa sam osluskivao iz susedne. Vestacko opterecenje sam pre godinu-ipo pozajmio coveku "za kraca testiranja" ali mu se "dobro pokazalo pa mu treba i dalje i ne moze da mi ga vrati" ... sad moram ponovo da sebi pravim da ne bih ostetio sluh.

Bice nekih izmena na semi i plocici jer jednim delom sistema uopste nisam zadovoljan. Dakle, ako je neko namerio da ovo pravi, savetujem da se jos malo strpi.
