Cek dulu R 5 watt, klau itu bagus kayaknya arus trafox kurang besar, bebanx berat, 15"x 2.

mungkin tr predrivenya soldiran kurang konek. cek pula berapa v bias -+ nya
RE: power amplifier - mahdumibrahim - 10-09-2015
R 5watt yg cocok buat power safari brp ohm/watt.?
Klo solderanx ok smw... tp cara biasx sy lom tw cara ngececkx... maaf soalx masih pemola

biasanya antara 0.33-0.5ohm
basis tr driver
tr drivernya (sebelum tr final) pake seri apa?

Sy pakek 5W/0,47ohm
TR driver pakek 41 + 42

ngukur bias + nya basis tip 41 dan bias - nya basis tip 42 terhadap ground

Untuk ngukur arus bias posisi di AVO analog saklar harus di posisi mana mas.? Coz pertm kalix sy mencoba ngececk BIAS
