Da bi tranzistor otisao u zasicenje potreban je napon na bazi Q5 da bude veci od oko 0.6V, znaci da ti je potreban ulazni napon veci od 1.88V. Probaj sa dve baterije redno vezane (3V), trebalo bi d aradi.

Stavi tako po predlogu @goshe,
pa dodaj još 1K pot ili trimmpot, i tačno izmeriš DMM-om kad ti počinje okidati DC protekcija, za POS i za NEG DC napon!
