Sprowadzone z Japonii (100V). Czysta klasa A, 30W. Lampowe brzmienie. Stan bardzo dobry, zero rysek. Wstawione złote bezpieczniki. Oryginalne też posiadam.
Recenzja z audiostereo :
"Na pewno sprzęt godny polecenia (choć trudno znaleźć ofertę w obecnej chwili) nie tylko z powodu bardzo solidnego wykonania,ale glównie z powodu znakomitego brzmienia (taki dźwięk kosztuje teraz BARDZO drogo)."
