Made of green onyx catalin.
The colour has changed to brown because of the influence
of sunlight. The original colour can be seen in the
picture on the right.
Catalin is a thermosetting polymer based
on phenol and formaldehyde. It was rather popular in the
1930s and 40s, among others for making jewelry. In
comparison with Bakelite, the colours are very beautiful,
but the material is very fragile, some colours fade
rapidly, and it shrinks.
With four metal tubes.
Suitable for AC/DC. For medium wave reception, 170-555
meters (540-1760 Kc). Chassis type RC-350-A. 3
Inch dynamic loudspeaker. Undistorted output power about 1 Watt.
To keep the small device as cool as
possible, a resistance wire is included in the power
cord. About 20 Watts of heat is "eliminated" in this way.
The radio was made in a
number of different colours: green (9X11), black (9X12),
crème (9X13) and brown (9X14). Model 9X6 has a wooden
cabinet.
