PIONEER SX-424

Vynikajúci vintage receiver PIONEER SX-424 v perfektnom elektrickom stave. Optický stav je tiež pomerne slušný, jediným menším nedostatkom je spodok pravej strany čelného panela, kde pôvodne boli nalepené akési čísla, po odstránení ktorých ostala táto časť čiastočne upatlaná /vidno na foto/. Aj na žáklade tohto je cena stanovená na 80,-euro.
