The 1700-series

The 1700-series in fact are sets with a built-in main amplifier, except for the 1731D which is a rare model and also a bit of a mystery. All sets from these series have only one motor and most of them have 2 speeds (3.75 and 7.5 ips). Some older models even have 4 speeds, which can be achieved by mounting the provided speed change sleeve adapter. I guess the mechanics of these sets are similar to those found in the 3000 and 4000 series.

There has been only one surround sound set in the 1700-series: the 1730D-SS (see: surround sound sets)

The 1700 (ca. 1966), the 1710 (ca. 1968-ca. 1970) and the 1720W (ca. 1970-ca. 1972)

The 1700 is strictly a Tube recorder; the 1710 has tubes and also a few transistors. The 1700 only has one VU meter which can be switched between the left and right channels, so they are stereo sets. Like I mentioned earlier they all have a built-in main amp and built-in speakers.

Both 1700 and 1710 are 4 speed capable by changing capstan sleeves and pinch rollers. The "W" behind the model number means this recorder has a wooden case. The "L" behind the model number means this recorder has a wooden case with leather finish.

The 1720W is an alternative version of the 1710W without tubes but with the older germanium semi-conductors which means it's a "solid-state" machine. The 1720W has a 6W built in power amplifier and built-in reel retainers.

The 1721 (ca. 1973-1974), the 1722 (1975-ca. 1977) and the 1722II (ca. 1978)

These recorders have 2 speeds and they are supplied with silicon semi-conductors. The 1721W has been available with both black and silver front panel. Cosmeticaly the difference between the 1721 and 1722 can only hardly be found. There specifications are alike as well. Maybe there have been some small internal improvements.

The 1722II is a very rare set and probably not sold in Europe. Its functions are just like those on the 1722 and 1721 sets. However, it looks way different. The 1722II uses the function levers which can only be found on the GX-4000D and the GX-215D sets, which make me think the 1722II is a 1977/1978 set.


1722 Specifications

The 1731D

The 1731 is together with the 1730D-SS (see surround sound series) the only 1700-series models with three seperate heads. Just like the 4000DS and similar sets, the 1731 also has the one micron gap head, seperated line and microphone input level knobs, sound on sound, auto shut off and two speeds. The difference between the 4000-series and this 1731 is the motor. The 4000 uses a single speed motor with a speed change sleeve while the 1731 uses a two speed motor.

Since there are no reel motors inside, you can fast forward and rewind the tape at two different speeds, which is little dangerous as soon as you change the speed from 7.5 ips to 3.75 ips during fast winding. I wonder why they made this model since the difference between the 1731 and the 4000 series is very little. Because of its size it looks a little more impressive than the much smaller 4000-sets though.
