    E' il primo amplificatore integrato a stato solido di Marantz quindi molto importante ed anche molto raro. Aveva molte facilities tipo separazione pre-finale , esclusione dei toni preamplificatore canale centrale-  collegamento per quattro altoparlanti - Quello della mia collezione e' col frontale color champagne ma molti erano color silver -tutti in alluminio spazzolato- Ottimo suono anche perche' nonostante il nome significhi trenta era accreditato di 60 watt per canale.
