The best place for this info (both sources and technique) is on the vintage page of http://www.audiokarma.org. Shain is the resident Marantz guru.

Yeah, the physical components are prone to wear but the fact that they lasted this long says a lot about 'em. I still say t hat the tuners in these old boat anchors are far, far superior to practically anything sold today. But, when you figure in ther cost back then and factor in inflation, they would cost a heckuva lot more in today's dollars.
Thanx for the link, I'll check it out.

Actually, I never thought that the switches on the Marantzes were all that durable. Started getting static on the volume control within the first five years, and one of the tape monitors began shorting out before that. Others switches have followed suit.

Can't deny though the sound quality on those units is superb, and aside from those switches, the overall build quality is very rugged. And the tuners on those vintage Marantzes are indeed better than anything I've used since then. The 2275 that my parents bought listed for $600 in 1976 (bought on closeout for about $350). Taking inflation into account, that would be nearly $2,000 today!
