DIR2 chip: YM3436D – this is a digital interface chip accept both AES/SPDIF and Y2 format signal widely use in Yamaha products since 1988. It is used in D2040 also. 2. YM6067: Parallel to Serial and serial to serial buffer x 2 chips, one chip support total 4 channels digital signal. 3. SM5803APT: 18 or 20 bit 8x oversample filter x 2 chips. 4. PCM63-KY or Y: DAC 20bit x 8 pcs; well know ladder type DAC which sound best back in 1989 period. 5. IV op-amp: M5238 dual op-amp. 6. Drivers op-amp: NE5532. 7. Resistor is 1/8W metal film resistors; not like D2020 use RMA resistors. 8. E-Capacitor: Elna Durex grade, I dissolder and verify the capacitors are still very good after 30 years. 9. Output couple capacitor is MUSE bi-polar Green capacitors. 10. Other film capacitor are either 5% or Soshin brand.
  2. znam da sam i ja imao isti problem kada sam se igrao pre desetak godina. secam se da je bila neka fora da se ubaci opornik ili dioda. davno bese Modding USB cable to power DAC with external PSU | diyAudio WWW.DIYAUDIO.COM Hello all.

  3. imas na KP za male pare: https://novi.kupujemprodajem.com/elektronika-i-komponente/elektronske-cevi/el-cev-philips-e180f-sq/oglas/139558385 ja mozda imam negde nekoliko komada, ali ko ce to sada pronaci u milijardu kutija
  4. jos da batali Sparkooos i stavi lampe u izlaz
  5. ja sam isto pre 10-tak godina imao Parasound sa PCM63, budzio izlaz sa Sowter trafoima I/V konverziju sa lampama u izlazu, nesto kao Audio Note sto je radio
  6. ja imam negde po fiokama taj PMD100 sa nekim adapterom koliko se secam, moram ga potraziti

  10. tako se kod mene bar pokazalo na raznim testovima, naravno da ne mora da bude pravilo, tako da treba probati u svakom slucaju u konkretnom sistemu
  11. takodje podrazavam ideju da aktiva ide samo na basove do nekih max 180Hz imho sve preko toga dramaticno utice na kvalitet zvuka probao, igrao se sa vrhunskim analognim i digitalnim skretnicima par godina i odustao sve je to bilo lepo na papiru i merenjima ali ubio srz muzike vratih se na pasivu i opet uzivam u muzici verovatno to ide sa ukusom, ja npr. ribone nikad nisam mogao da slusam

    A very simple method would be a relay switched B+ with the relay being triggerd by the bias voltage. Either have the B+ on a spearate transformer which is switched on through the relay. Or have the relais in the ground connection to the center tap. If the bias voltage fails, the relay opens and B+ is drained through bleeder resistors and power tubes. If the bias voltage doesn't come up at turn on, the relay stays open a ako neces puno da se patis imaju i one gotove plocice za automatski bias Auto Bias Modul for two Tubes (Single pcb to Control 2 Power Tubes) | eBay WWW.EBAY.CA Find many great new & used options and get the best deals for Auto Bias Modul for two Tubes (Single pcb to Control 2 Power Tubes) at the best online prices at eBay!
