Additional Details


This little Italian machine is rather special. Not only is it made in cheesy white and grey plastic with colourful buttons, it also has some rather interesting technology inside.

The machine is quite small and can only take up to 5″ reels. As a consequence the three speeds include the very slow 15/16 ips. where the sound quality is fairly average, but if you are satisfied with a cheap microphone or AM radio it might be sufficient.

An identical model, the G-682 (pictured) featured a built-in radio tuner (second image, above). The aerial can be seen at the bottom right hand corner.

A special feature of these two is that some of the mechanics are solenoid operated which makes it possible to remote control rewind and start/stop.

The level meter has a 20 x 10 millimeter scale with green, yellow, and red colour for low, middle, and high level.
