One of the most popular of the GX-600 series, the GX630D (despite its model number) is an earlier version of the GX-620 and the 10½ reel” version of the GX-270D, without auto-reverse functionality.
The capstan motor was of the direct drive type and provided two speeds, 3¾and 7½ ips.
A Dolby version, the GX-630DB was available a little later, and also a half- track version, the GX-630D/PRO. This ‘PRO’ version had a larger diameter capstan shaft and provided the higher speeds of 7½ and 15 ips.
