Description
Power Amplifier NOOSFERA A12
Прекрасно работает, ток покоя 250-300mA.
Очень внимательно с выходными транзисторами. Подделки присылали 4 раза. У транзисторов ВК особенная цоколевка. Усилитель довольно дорогой в построении из-за ВК. Все резисторы 1%. Кондесаторы Epcos. Конденсаторы SMD NP0, на звуке никак не сказалось. Все маломощные транзисторы подобраны по h21e. C10, C17 - 16V
