Description

It was the Japanese who introduced the concept of vertical operation, and fired the imagination
of the average enthusiast, these looked more professional, and were bought because of their looks as much as anything else.
Ferrograph were slow to respond to this challenge, when they did it was too little too late.  The introduction of the Series 7 in the late 1960’s was ill conceived, and poorly implemented.
The later Super Seven tried to address some of the shortcomings, but it was too late to repair their damaged reputation. Enthusiasts who had always been loyal to Ferrograph moved their allegiance to Revox, Tandberg,
Sony, Teac, and Akai.
