Citao sam:
It is important that the filter capacitor has low ESR and low ESL so that it maintains
low impedance at high frequencies. For this reason it is unwise to employ only a film
capacitor. A film capacitor should be bypassed with a large-capacitance ceramic NPO
capacitor. ( Designing Audio Power Amplifiers, Bob Cordell)
Dakle, da probas bajpas kermickim kondenzatorom ( NP0) ili mozda bolje nekim stirofleksom npr 10nF preko film kondenzatora u izlaznom LC filtru?
