The 1710 was a quarter-track stereo recorder of hybrid design, using tubes for the power amplifiers and bias oscillator and silicon transistors in the preamplifier stages.
It had three speeds (7½ , 3¾ and 1 7/8 ips) and speed change was implemented by the motor switch and the addition or removal of a capstan sleeve. Reels of up to 7″ could be accommodated.
The internal amplifiers produced 5 watts per channel and the recorder had two 5 x 7″ side-mounted speakers.
Models were prefixed with a W (wooden case) or L (leatherette covered wooden case).
