Made of Pollopas (more information
about this plastic below). The cabinets are white and chestnut brown and
the loudspeaker grille and knobs are red.
The term "Super Boum"
indicates that the radio is capable of reproducing low
tones. It also means "Big Party".
The radio, with its colorful appearance, focused mainly on young
people. It was presented
at the Foire de Paris, which was held from May 21 to
June 6, 1949. In an interview in 2005 the son of the
Mr Véchambre, told that the Super-Boom at the time did
not receive the success expected by its creators.
For reception on medium wave (180-555
reaching the end of the medium wave scale, the radio
automatically switches to a small segment of the long
wave where the popular station Radio Luxembourg used to
transmit on 1293 meters.Currently,
RTL France can be heard in that segment, at 1281 meters.Further stations on
the long wave can not be received.
There are also models with a complete
long wave;these were probably made
later than 1949.
In 1948 a reclassification of a large
number of frequencies was agreed in Copenhagen.In March 1950 these changes came into
effect. The white radio still has an old station
layout; the brown
radio has a new layout.
The intermediate frequency is 472 kHz.
A scale light (6.3 volts, 0.1
A) rotates together with the pointer.
Antenna, earth can be
connected at the rear.
The knobs from left to right: on/off/volume, tuning.
The Ticonal speaker has a diameter of 12
cm. Radialva also sold a loudspeaker, designed in the same style as the
radio. The knobs have no function here, they are
fixed. (see photo on
The receiver was made in a number of
colors: brown/red, brown/white, brown/mint green,
white/red, white/mint green, white/blue and white/red.
The original price was FFr .
The brown and red version has a
sticker with the name of the seller: F. Jeanson, Radio
Gambetta, 144 Rue Gambetta, Reims.
Pollopas is the trade name of a duroplast
plastic based on urea-formaldehyde resin. From the
beginning of the 1930s many consumer products were made of this
material when it was manufactured on a larger scale by Dynamit-Nobel in Germany from 1929.
The basic ingredient was the same as that of Bakelite,
but Bakelite needed to be pressed with a
filler using very high pressure and temperature.
Pollopas needs less pressure and temperature, making it
easier to add dyes.Probably the name
is derived from the name of the discoverer, the chemist
F. Pollack. Catalin resembles Pollopas, but can not be
used in combination with food.Catalin is also less firm.
