  1. Zen Mod

    Završen preamp

    pazljivo procitati drugu stranu to je ono sta ja cujem kao potvrdu "signal energy preservation" naravno - kao i uvek - vase misljenje moze i mora da se razlikuje
  2. 25g od mature u srednjoj ; dosao jutros u 5 kuci ;)

    1. Zvu

      Zvu

      Živi se mladalački :D

    2. gaggia

      gaggia

      Иххх, само 25!? Деда, лажираш резултате!

  3. prebaci temu negde drugde i z off topicau know how ili sta vec
  4. 100oooogodina mature

  5. samo metalni deo kutije i trafosve ostalo odnela Braca Cigani
  6. ja sam takav rastavio u paramparcad pre 2-3 nedeljenije nizasta drugo - pozar u kuci
  7. Deda -mora da je mnogo slana ta sunka sto si sinoc kusao .......
  8. Sloba nam je valjda stigao s puta poslovnoga ......... kazem nadam se da jeste ...... i da sad lada u dvoristu sa nogama u lavoru , i pivom u ruci .......
  9. be patient day or two - then we'll have proper schematic with proper nomenclature , so explaining things will certainly be easier ;I'll make small batch of pcbs , so you can count on that ....... but be aware of possibility that someone on big DiyA came with closer approximation of real J2 .I intentionally didn't count parts in J2 , so I use it as general guide , really wanting to Babelfish it , not clone it .edit - all values of pots , along with dedicated series fixed resistors , are chosen to prevent any smoke scenario

    ja sam odustao od otpornika u anodi radje i ekser
  11. nece - ne boj se - ene je rastavljena ce sledece pravimo Little Donut
  12. Zen Mod

    driver za 300B

    zadnji put kad smo pricali o biznisima , pominjana je stamparija ....... ako nisam izlapeo ....... ( a jesam )
  13. Zen Mod

    driver za 300B

    a moram malo da se zekim ........ kako stamparija ?
  14. slobodno koristi zice (1,5kvmm) od plocice do mosfeta do 50mm a da ne moras misliti na gate otpornik - da ga montiras posebno kao sto rekoh - imas detaljne slike u pomenutoj temi
  15. da montiras ruju direK na Cu vinkl , pa stavis veeeeeliki liskun izmedju Cu vinkl i hladnjaka ?
  16. pretpostavljam da imas fotoaparat - kojem ne treba razvijanje filma i izrada fotki u labu ? Babelfish za Hifish-a ; tamo je koristena Pezante dissipante hifi200seljackatalijanska kutija imas slika na gledanje , pa mozes mnogo da zakljucis iz samog gledanja istih
  17. Tea- just few thoughts ...... as you can always see from Papa's schematics - he always counts on selected parts ; same is here ; value of drain resistor in input LTP is dependable of exact lower output Jfet Ugs value ; same - value of resistance in paralell to CNY bjt is dependable of exact upper output Jfet Ugs value . so - procedure for making functional Babelfish J2 is something as : 1. test and choose output Jfets ; according to their respective Ugs values - 2. preset input LTP resistance and CNY's parallel resistance 3.preset input LTP CCS at 20mA ; then 4. solder outputs in place and proceed with proper power up procedure #3 demands some tricks how to , with auxiliary PSU ...... or just setting programming resistance in CCS to ~ 0V65/20mA=32R5 more to come - with proper schematic , with parts nomenclature
  18. just best practice but - I didn't tried really mismatched ones ; maybe I will , but not so soon ...... maybe because I don't have really mismatched ones I know that they're everywhere from 1V2 to 1V9 , at 2A in any case - I think that real and valid answer you can get only using THD meter , and comparing best and worst case
  19. not exactly matched you can see their Vgs-es at 2A on pictures
