Description
The Ferrograph Super Seven addressed many of the problems, and shortcomings that had blighted the original “Series 7″.
The move to the higher capacity 10½ ” NAB reel size was very welcome, particularly for those recording at 15 ips. This move added a
further control to the panel. At the side of the variable wind knob is a reel size selector, which adjusts the torque of the motor to suit the
heavier 10½ ” reels.
Mechanically, this model is the same the Series 7, albeit beefed up to ensure correct and safe handling of the more professional reel size.
Metering was improved, at least in physical size if not performance.
