Back in the mid to late 60's, my father purchased some equipment from a radio station after it was re-equipped. In the mix was a rack (I was a kid and it seemed 10 feet tall, but probably about 6 feet), equipped with two magnacord decks (at least I recall the two electronic rack pieces were magnacord).

Each deck could handle 14" reels (10" reels looked small in this thing). The decks mounted such that the reels were top/bottom, not left/right like usual decks. The tape threaded through the heads on the right of the reels, had a twin capstan drive, typically half track mono, with a foil sensitive auto-reverse.

The electronics were designed such that when the tape on the top deck completed, the bottom deck would take over.

The decks did resemble, vaguely, an old Ampex deck mounted 90 degrees counter clockwise, but the Ampex didn't have dual capstan drives.

Anyone recognize this description? It's possible the decks were some other brand, but the electronics were magnacord, I don't know.
