Typeplaatje
The economic situation in the
Netherlands in the 1930s was not very rosy, and the factory was
confronted with strikes and wage cuts.On October 12, 1931, a strike broke out among
150 factory girls working at N.S.F. at the
assembly line.As a result of a wage
measure, their wages were reduced by 10%, while the the amount
of work increased.After commitments
from the company and allowing a greater role for the union
movement within the company, the strike ended after a short
while.In March
1932, staff again had to agree to a cut in wages.
The chassis of the radio is the same
as that of the Philips 720A/730A.It was therefore the
first NSF radio that was made on the basis of an existing
Philips chassis. Date stamp
on one of the condenser blocks: December 16, 1931.
The original price was f
275-.The
Philips 730A cost the same.Around
900 radios were made.
In Belgium, the receiver was sold under
the brand name Aristona.
The first owner bought
the radio at Jan Langkamp, Emmastraat 318-320 in
Enschede, in February 1932. An advertisement of this
shop for the NSF Hilversum 5 in Twentsch Dagblad
Tubantia of December 4, 1931, is shown below.
