WR
1 (WR 1/P) - Wehrmacht troops entertainment broadcast
receiver. Frequency bands: LW (150…425 kHz),
MW (517…1540 kHz) and
SW (5.9…15.5 MHz). Manufactured by Blaupunkt
from late 1941 as a replacement for WR 1/T.

The
WR 1 broadcast receiver was designed by Blaupunkt in 1940. It was
a high-quality rugged 6-tube superhet capable of indoor and field operations.
Letters "WR" stand for Wehrmacht-Rundfunkempfänger.
Using
at first Telefunken metal tubes of so-called "11th Series" (DCH 11, DF 11, etc.) made by Telefunken, the WR 1 was redesigned in 1941 for the new glass
tubes of "25th Series" (DC 25, DF 25, etc.) with loctal base made by
Philips.
Because
on the outside both old and new models of WR 1 receivers looked exactly the same
yet requiring different spare parts (spare tubes, etc.), Blaupunkt had to mark
the WR 1's in a special way. The receivers of the old model were marked by big
letter "T" at the top left corner of their front panels while
receivers of the new model were marked by big letter "P".
Please
note that all the WR 1 receivers of Blaupunkt manufacture thru all the
production period (1940-1943) had just "WR 1" symbols on their factory
labels. There are three different versions of WR 1 factory labels known to us
which differ in the way of indicating the Manufacturer's only.
It
is important to understand that abbreviations "WR 1/T" for the
old model and "WR 1/P" for the new model of WR 1 by Blaupunkt were
used by Wehrmacht in documentation only (!!). Apparently it was a
combination of "WR 1" symbols from Blaupunkt factory labels and big
letters "T" or "P" from the receiver front panels.
Vacuum
tubes used in WR 1/P receivers were Philips glass tubes DCH 25, DF 25 (2 pcs),
DAC 25, DC 25 and DDD 25. There was the 7th tube in WR 1/P, a DF 26, which
served as microphone amplifier and provided for use of an external record
player.
While
standard WR 1/P broadcast receivers covered LW (150…425 kHz), MW (517…1540 kHz) and SW (5.9…15.5 MHz), on special order it was possible to convert the WR 1/P into a Short Wave communications receiver covering 1.5...21.7 MHz in three
frequency segments - 1.5...4.6 MHz, 4.6...10.5 MHz and 10.5...21.7 MHz. Special
tank circuits and scale would be factory installed in WR 1/P for such special
order.
The
WR 1/P could be powered from AC or DC networks of 90V to 250V or from 90V dry
battery and either dry or storage battery for filament. Two ENL dry cells could
be used or a choice of storage batteries including 2 В 38, 2,4 NC 28, 2,4 NC 58
or 4,8 NC 10. Car batteries of 6VDC or 12VDC could also be used with WR 1/P
receiver.
WHD
= 395 х 485 х 283 mm. Weight with dry batteries - 32 kg, weight without
batteries - 26 kg.
