Достоинства: Очень аккуратная плата усилителя. Все соответствует описанию. После проверки можно дополнить.
Недостатки: Мал радиатор, но это легко исправить.
Достоинства: Прям малыш))) Брал для небольшого саба. Прогнал через частотный генератор. Слышит 20-30Гц, всплеск от 45-60Гц, подъм на 70Гц. Пойдет, некоторые и ниже 35 уже не слышат.
Недостатки: неудобный регулятор для увеличения громкости, неудачная клемма для подключения питания и входного сигнала
Комментарий: аккуратно собран, какое то усиление даёт.
