I own this same pair.

Profound sonically and the cabinets are truly monsters.

no photos but i received them from their original owners where they were used in a demonstration in 1976 or thereabouts and then clearance-sold as not new.

they look just as the pdf you posted and i'm in need of radiator units so i'm afraid i will have to build them myself. i don't play them as a result of this. can't expect to find loose parts like this anywhere either, especially at ess it's own self since they're so disorganized and caddywhompus in the facility.
