    Van _Helsing...pogledaj link u mojem prvom postu,i otprilike tako bih zeleo da se reataurira,manje vise... http://www.sansui-vintage.com/article_info.php?articles_id=3&osCsid=e90053b68a3edcd3b7ea505502835b6c

    Ima li u Beogradu ili u drzavi Srbiji,majstor,tehnicar,inzinjer..koji zna ume,hoce ,voli da se bavi izazovima,ima iskustva i nije od onih "take teh money and run"..? Naime,zelim da restaurisem,pojacalo AU-X1,otprilike kao sto to radi gospodin Kale iz Katel Sucurca iz Hrvatske..Oni koji su pratili njegove postove ovde ili na slicnim sajtovima znaju o cemu pisem.. http://www.sansui-vintage.com/article_info.php?articles_id=3&osCsid=e90053b68a3edcd3b7ea505502835b6c
  3. Problem resen,nabavljen trafo,montiran u kuciste i radi savrseno,verujem mnogo bolje od originalnog,koji se fabricki isporucije..
  4. E to ne bih znao da kazem,da li su uracunali,pad napona na izlazu,nazvacu ih sutra,jer nisu radili zbog praznika..ovo je fotka motora,sa podacima.
  5. ULAZNI NAPON JE 220V..IZLAZNI JE 16V..ALI AC,ZNACI NIJE DC..500mA..ISTI TIP ISPRAVLJACA KORISTI SE I ZA PRO-JECT PHONO BOX MKII. NARUCIO SAM OD TRAFOMATIKA,DA MI NAMOTAJU TRAFO SA ISTIM SPECIFIKACIJAMA,SAMO STO CE BITI MALO JACI,UMESTO 8W,BICE 10W..NADAM SE DA TO STO JE JACI,NECE DA IMATI POSLEDICA PO RAD MOTORA.
  6. Ako neko zna,kako da nabavim i gde trafo ili neku zamenu ,ne mora da bude original,neka mi javi u poruci. Hvala unapred.
  7. Kupujem napajanje za gramofon Pro-ject : input AC 220V output AC 16V/500mA ponude na tel: 064 110 66 40
  8. Sta reci o ovakvim i slicnim budastinama..osim da dok ima ovaca ia i vune...efekat ovakvih napravica,je 0...ali ko voli neka plati i neka se tesi da to stvarno ima smisla.
  9. Drvo kao materijal za zvucne kutije,veoma retko se koristi,ne zato sto je skupo,i sto zahteva dobru konstrukciju vec zbog mnogo losijih akusticnih karakeristika nego sto je to kod medijapana ili iverice.Gustina ,materijala,kao sto neko rece je mnogo ujednacenija u svim delovima povrsine.nego kod cistog drveta,upija neuporedivo bolje vibracije,recju ne zvoni...Sonusi ili Diapasoni su dizajnerski savrseni,izrada vrhunska,zato i sama kutija kosta bar 5 puta vise od drajvera i elktronike u njima,sto se i tekao odrazava na konacnu cenu...o zvuku ne bih ,ukusi i sta ko preferira je licni dozivljaj..
  10. Stvar ukusa..licno,crna boja je moj favorit,ali ako je uredjaj vrh..onda nisam gadljiv ni prema srebronoj,sampanj.. ..konkretno ovaj Sansiji je..uhhhhhhhhh..
  11. Jedan od ,kazu mnogi,najbolji...istina ili...jos jedna od zabluda...?
  12. Zanimljiva rasprava,samo me zanima kolko sve to ima veze sa HI-FI...osim da kao i na svakoj temi koja se ovde otvori,dodje do svadje..???

    hmmm....slazem se sa Pepom,glede opaske u vezi 901...nesto nije bilo debelo u redu sa njim ili necim u ostatku sistema.. imam AU-901,i to pojacalo svira i vise nego odlicno,mozda i poslednje zaista dobro pojacalo koje je Sansui izbacio na trziste krajem 80-tih kada si poceli da posustaju..Naravno tu ne ubrajam pojacala iz alfa serije iz 90-tih,koja su izvan konkurencije i veoma malo ih je bilo izvan Japana,u prodaji. za apsolutnu preporuku je pogledati link koji je Kale dao,gde se vidi AU-X1 u svim fazama restauracije..radovi su pri samom kraju..
  14. The sound pressure output is measured at (or mathematically scaled to be equivalent to a measurement taken at) one meter from the loudspeaker and on-axis (directly in front of it), under the condition that the loudspeaker is radiating into an infinitely large space and mounted on an infinite baffle. Clearly then, sensitivity does not correlate precisely with efficiency, as it also depends on the directivity of the driver being tested and the acoustic environment in front of the actual loudspeaker. For example, a cheerleader's horn produces more sound output in the direction it is pointed by concentrating sound waves from the cheerleader in one direction, thus "focusing" them. The horn also improves impedance matching between the voice and the air, which produces more acoustic power for a given speaker power. In some cases, improved impedance matching (via careful enclosure design) lets the speaker produce more acoustic power. preuzeto sa Vikipedije.
  15. efikasnost zvucnika i osetljivost istih nije isto. Loudspeaker efficiency is defined as the sound power output divided by the electrical power input. Most loudspeakers are inefficient transducers; only about 1% of the electrical energy sent by an amplifier to a typical home loudspeaker is converted to acoustic energy. The remainder is converted to heat, mostly in the voice coil and magnet assembly. The main reason for this is the difficulty of achieving proper impedance matching between the acoustic impedance of the drive unit and the air it radiates into. (At low frequencies, improving this match is the main purpose of speaker enclosure designs). The efficiency of loudspeaker drivers varies with frequency as well. For instance, the output of a woofer driver decreases as the input frequency decreases because of the increasingly poor match between air and the driver. ostetljivost: Driver ratings based on the SPL for a given input are called sensitivity ratings and are notionally similar to efficiency. Sensitivity is usually defined as so many decibels at 1 W electrical input, measured at 1 meter (except for headphones), often at a single frequency. The voltage used is often 2.83 VRMS, which is 1 watt into an 8 Ω (nominal) speaker impedance (approximately true for many speaker systems). Measurements taken with this reference are quoted as dB with 2.83 V @ 1 m.
