Description

The 1720 was available in two versions, suffixed “W” and “L”. These suffixes referred to the type of case, wooden (W) or leather-finish over wood (L).
It was a quarter-track stereo recorder with a built-in solid state 6 watt power amplifier (3 watts per channel) and two 7 x 5″ speakers.
The 1720 could handle reels of up to 7″ and the built-in reel retainers meant that the recorder could be used in a vertical position. Three speeds were available. 7½ , 3¾ & 1 7/8 ips, selectable via the two-speed motor in conjunction with a removable capstan sleeve.
