Made by
the Rijnlandsche Ontvangtoestellen Fabriek,
Langebrug 32a/b, Leiden. The R.O.F. was active from 1929
until 1932. In this period the company promoted a license-free industry.
|
|
The company originated from the radio department of
Peltenburg of 1793, a piano trader that launched the
Novavox radio in 1928. Owner of the
R.O.F. was Mr. C.A.
Mulder from Oegstgeest. |
|
Except
loudspeakers, the R.O.F.
made radios such as the R.O.F.
People's Receiver and the R.O.F.
WI. In the
fight against the Philips patents, the R.O.F.
in 1930 made the R.O.F.
GI, a 4-lamp device that made use of
Idzerda's patent-free
design. |
