    Tamsak done kaibigan lahat ba na amplifier design na nakafloat ang feedback ckt nya ay pag sukatan mo ng vbe ang opt ay wala kang masusukat kapag wala pang audio signal lody tnx tama idol i share mo na lahat ang alam para pag tinanong ka ni lord kng hindi ka nagdamot sa kapwa mo masasagot mo ng derecho si lord lody

    Sir good eve po. Pano ko po i apply yan sa rockola expandable sir. May distortion po kasi ang amp kapag low volume plng. 54vdc pos/neg lng ang supply ko sir. Nung ginawa kong 24v ang zener na regulator ng differntial gumanda ang tunog kaya lng uminit nmn mga driver. 0.1 po pla current vbe ng output trans (5200/1943) salamt po

      Para s akin yung may bias kahit walang tunog tulad ng power amp design...pero wala nmn poblema yun aslong na normal nmn vbe voltage pag may audio na...at dwpnde rin yan s design ..kaso kdalsan kz power amp may bias voltage s vbe habng stanby mode...pero yung racola mababa lng din yun pero quality din nmn nsa calubration padin aslong n gud quality at matibay wala poblema yun

    Sir, newly diyers lang ako. May gi awa ko yong mgm philippines modified 737. Hindi pantay sir ang +Vbe at - Vbe. Sa (Vbe +) ay 0.018 some thing like that. Yong (Vbe -) ay 0.354 like that. Ano sir gagawin ko para mag pantay? D ko alam saan ako mag lagay ng bias resistor base sa sabi nyo na sa deferential stage po.
