Ampligraph Reel to Reel Tape Recorders

Ampligraph appears to be very short-lived US tape recorder manufacturer that we found in a buyers guide. As compared to so many lower-priced tape recorders in 1961, the Ampligraph 66 at $335, looked to be worthy of investigation. Very little information is available, however this article,  also from 1961, gave us a clue, that something half decent was produced. Who knows if they got many out the door.
