AC30 radi u A klasi! Mozda su to kakva naklapanja sa stranih foruma da nije u A klasi. Sandro, sjeti se koliko su te cetiri EL84 proizvodile topline za samo 30 W snage, a probaj koliko ti ovih 40 W sa Kettnera proizvodi topline? Sigurno manje! Zasto? Jer Kettner ne radi u A klasi kao AC30! Pozdrav.

moj dsl401 sa 4xel84 se toliko uzari da se skoro opecem na front panelu....pa ne radi u a klasi

"It is interesting to note that the schematic in the Pittman book clearly says "12.5V at 30W, 10V quiescent", indicating that there is a large change in average current draw between idle and full power, as would be expected in a class AB design, yet many people still claim it is class A. "

"These findings prove that the Vox AC30 circuit design is indeed, a class AB amplifier, although, to be fair, it is biased a bit hotter than most fixed-bias class AB amplifiers."
