Ukw. E. e 1945 Restoration |
Nr. 245973 |
This receiver was manufactured in 1945, therefore one can expect inferior components and materials. The solder is usually of inferior quality, but is still better than the electro-fusion spot welding that took place at the end of 1945. As were most post 1941 Ukw.E.e receivers, this one was a "Gelbstrichgerät", or "yellow-stripe device" with allowed it to be used through an intercom box without assistance of a power amplifier, since it used the detector as an amplifier circuit. The restoration process is described below:
|
|
|
 |
The receiver's face-plate. It has been cosmetically restored before I started working with it. |
|
 |
The first problem was a missing capacitor in the power stage of the receiver. |
|
 |
Here is the new capacitor and also the old one as well. Both have been restored and have brand new capacitors inside of them. |
|
 |
Tuning the resonant frequency of the oscillator. |
|
|
|
Heterodyne frequency is 183.8 Khz too low (receiver set to 30 MHz) and must be adjusted.
