5. Czechoslovakia after WWII
Marco Berti (Italy), Martin Hajek,
and Antonin Svec (Czechia) provided me
with some some historical information about the radio plants and the
political and industrial situation in Czechoslavakia at the time of
birth of some of my radios.
Czechoslowakia had always been technically advanced, there
were many radio factories and the population was among the most
educated and culturally advanced of the world; only after the Second
World War, under communism, there was a decline.
After the last Nazis escaped and the Russians entered Prague on May 8,
1945, the Czechs had free elections in early 1946, Benes was prime
minister and the strongest party was the Communist. A couple
of years of freedom followed, but in early 1948 Stalin decided to
"normalize" Czechoslowakia, Benes mysteriously died and
Gottwald, a Stalin adept, took complete power. He was so bound to
his big idol that he even died just one week after Stalin (in 1953).
Philips Elektra and Tesla
The process of abolition of private factories had begun well before
Gottwald's coup: in 1947 most of the formerly private enterprises had
The Philips manufacturing infrastructure became the Tesla radio plants
and started (or continued) the production of small bakelite radios
using a then innovative Philips circuit.
During the first years of the Second World War, Philips developed a
series of new tubes and a new circuit using
The revolutionary circuit was adopted in many sets, starting with
the Philetta 203U of 1941, produced in various countries including the
then "Protectorate of Bohemia - Moravia".
Also this Talisman 305U was designed, in the Tesla Hloubetin plant in
Prague, on the basis of the UCH21, UCH21, UBL21, and UY1N tubes.
However, what made this little radio so attractive and famous was not
the circuitry inside, but its compact and elegant design; compare the
radio to the Philips 208U (1944).
Virtually the same design and the same chassis were used in four radio
types (with different cabinets): the 305U, 306U, 307U, and 308U.
Production of the 308U continued until 1958 and altogether over one
million radios of this design were sold.
In the Western countries the circuit was abandoned since 1950.
In Czechoslovakia, with no competition and no import-export with
competitive countries, innovation was not a major issue, and
besides, the radios were actually very good and well built.
Tesla used the four-tube principle (with addition of a magic eye
in some models) until the late nineteen fifties with only minor
I was even reported implementation with the Noval tubes ECH81, ECH81,
EL84, but have never seen such a radio.
I have visited the Czech and Slovak republics several times for my work
and have brought home the following radios from there.
