Recommended Posts

Terminasem un transformator PP 2X6L6(6P3S) 20cm-patrati Raa=6k2,numai bun pt un test EL84-SE,rezultatele se vad mai jos(nici mai mult nici mai putin de 20Vvv-sinus/8_ohmi=adica peste 6W/8_ohmi ,nelimitat dar in prag de limitare),osciloscopul Y=2V/div,frecventa 1khz_sinus.__320V-anodic__8,9V catod(negativare automata) Rk=165 ohmi/2W__320V-G2 prin 470_ohmi__Ra 6k2/Rs_8 ohmi__Rg1 470K__Ug1 atac 4,5Vef__Ps nominal 6W.__Clasa este A negresit.In motaj nu se afla decit lampa finala(acesta lampa in aceste conditii in lipsa semnal=versatester oprit , NU are de suferit nu se inroseste anod sau G2 !,deasemani nici la puterea maxima NU are de suferit ! ).__Aceasta putere(6W) este aproape imposibil de obtinut(EL84-SE) pe sectiuni mai mici ,practic transformatorul de iesire in acest caz poate fi considerat IDEAL.__Asa ca atunci cind se vorbeste de 5W in cazul EL84-SE i_mi vine sa rid...(cu trafuri de duzina ,recuperate-cadre-retea-etc-etc="BLASFEMIE"). __Si traful mai jos...(fara intrfeier,desigur).

Incearca la Dj_Dog (nu are de ce sa nu le faca-depinde daca poti sa sustii/i_ti convine , costul,mai ieftin decit la el nu cred ca le vei putea face !?) "bobinatorul de servici"...

Nu voi folosi acest trasformator in SE(a fost un experiment pt a demonstra ce se poate obtine in EXTREMIS din EL84-SE ,dar desigur cine doreste poate folosi acest model de transformator in SE fara nici cea mai mica problema=rezultate garantate-din acest motiv am stipulat si valorile in experiment).
