Technics SE-A1 power amp si SU-A2 preampul de care ziceai - au fost fabricate numai 5 combouri, la vremea aceea si precum si acum in 2009 sint 2 componente de referinta, uite ce controale ai pe preamp ! Iar power ampul e si mai si ! La vremea aceea - 1978-1979- costau extrem de mult pt cei citiva care le-au avut !
