Blaupunkt WR1-T
 

This is one of the largest, most complex and multi-featured troop entertainment radios with the following features:

  • The WR1-T was capable of drawing power from multiple sources based on the power grid of the occupied country.
  • It was able out output sound to any number of external devices, and play music from gramaphones or other playback machines.
  • Different types of antenna systems could be connected to the WR1-T depending on what was available.
  • The receiver could catch stations on both the short, medium and long wave bands.
  • The built-in speaker was loud and powerful. Headphones could also be used.
  • The built-in voltmeter told you if your power setting was correct for utility power in that region.
  • The WR1-T could be powered with either battery or utility power.

We restored this WR1-T internally to full working order and power supplies were built for it to fit into the battery compartments.

As far as I can tell, the only difference between the WR1-T and the WR1-P are the vacuum tube types that can be used in these receivers, and that is why I believe the "T" or "P" designation only describes the vacuum tube series used inside.

Here is the Voltage source switch. The "BATT." setting switches to battery power. The Netz setting is the first one to be used under unknown utility power conditions.

These are the volatage settings from the WR1-T manual. There is no explanation as to the absence of the 12 setting.

 

 

 
This is the frequency scale showing short, middle and long wave frequencies. Different cities in Germany and Austria that could be received are shown on the scale. To the left is the rare WR1-T voltmeter, which worked well. It showed fillament voltage automatically when the receiver was switched on, and should show within the red range. When the blue button is pressed, the volt meter showed Anode voltage, which should be in the blue range.

 

 
The label reads: "Attention! When operating from utility power, turn the switch below to the right slowly, until the Voltmeter indicator reaches the red mark". The connector above the sign is the headphone jack, which accepts both plugs and naked wire connectors.

 

 
On the left is the wave range switch: Tonabn. (aux. input such as a record player), Shortwave, Middlewave, and Longwave. To the right of this swich are the ground, antenna, and antenna switch connectors. Above this connector is the antenna range switch.

 

 
Volume, tone adjustment and frequency tuning knobs. Below are input jacks for either a microphone or a record player.
