netyčia pastebejau, kad šis T.M.A. stiprintuvas (taip pat irr 500.1) yra B klases

jeigu gerai pamenu tai B klase naudoja mažiau elektros, automatiskai mažiau krenta itampa ir galios daugiau atiduoda, bet kokybe nuo nukencia. nemoku tinkamai issireiksti bet -

AB klasė tarsi atstovas/tarpininkas tarp kokybiškos A klasės ir ekonomiškos B.

ir dar pridesiu ka radau


"CLASS 'B'
A class 'B' amplifier uses complimentary transistors for each half of the waveform. A true class 'B' amplifier is NOT generally used for audio. In a class 'B' amplifier, there is a small part of the waveform which will be distorted. You should remember from an earlier page, that it takes approximately .6 volts (measured from base to emitter) to get a bipolar transistor to start conducting. In a pure class 'B' amplifier, the output transistors are not "biased" to an 'on' state of operation. This means that the the part of the waveform which falls within this .6 volt window will not be reproduced accurately. The output transistors for each half of the waveform (positive and negative) will each have a .6 volt area in which they will not be conducting. The distorted part of the waveform is called 'crossover' or 'notch' distortion. Remember that distortion is any unwanted variation in a signal (compared to the original signal). The diagram below shows what crossover distortion looks like."
