Stenorette 2000. Cassette tape recorder.
Made in Germany in the early 70's. This apparatus is
particularly interesting because it uses non-standard
microcassette (Steno-cassette). Size it more modern
microcassette, but much less compact cassette. It can
record one track for 30 minutes at a speed of 2.38 cm /
sec. The cartridge design does not allow to curl up and
make a second track record, but it has a built-in tape
counter. The counter has a complex structure, it uses a
few gears and worm screw. Almost all body parts and
plastic tapes. Dimensions 65 x 45 x 10 mm, Weight 23 g. gears and
screw visible on the enlarged photographs.
Also embedded in the cassette are
contacts which are closed metallic coating on the tape
at the end of winding. The contacts are on the lower
side of the tape, and when it is inserted, pressed to
the appropriate terminals on the recorder. During
recording when the tape runs out, a
warning is included on this tone. The same
signal is also included in the case
where the recording is enabled but no
cassette is
inserted.

external power supply. Dimensions recorder 150 x 80 x 38
mm. Weight 500g without batteries. Power 4,5 v.
Versatile and erase heads together in the piece. The
device produces a very good impression and appearance,
and quality construction. The body is made of cast metal
and good plastic. Inside and it looks very good. The design is complex,
and performed in German quality. Works staff is also
quite decent, pleasant sound, the microphone sensitivity
is good, the volume is also lacking. Circuit collected
13 transistors. Two output transistor type AC187 and
AC188, the rest BC238 and BC308. In this case the
amplifier is used only 6 transistors, and the rest in
the generator and the erasure in the scheme of motor
control. Unfortunately the recorder is not forward, but at the
time it was considered normal. Included with the tape recorder I got

tapes, and original headset in a plastic box. In the
dock there are two connectors, one for headphones, the
