Hallo,

Torn.E.b.  Portable short wave receivers (Tornisterempfänger Berta) have been widely used by German Wehrmacht during world war II . During last part of the war soldered connections were partly impossible by extreme shortage of material. So in some manufacturing places compartments were fixed by spot welding. Restauration of these receivers is very difficult or not possible.

Pictures of these spot welding have been published by Wolfgang Schröer ( Tornisterempfänger “Berta” Band I , Genealogie-Aufbau-Varianten, page 272).

Picture of a Torn.e.b. of 1944 .

Fellow Radiophiles:

Robert Lozier (kd4hsh) is one of the foremost radio restorers and collectors in America. The quality of his restorations even extends to very accurate reconstructions. I have seen some of his extraordinary work at american antique radio meetings.

Robert asked me to post the following inquiry. 

Regards,

-Joe

Hello, 

I am trying to find any information on how and why welded copper connections were made inside an Iskra 53 ( Искра 53 ) four tube broadcast receiver made at the Aleksandrov Radio Works.  The particular receiver I have was assembled in 1958.

This is an assembly technique that I think is unknown to amateur historians of vintage radios here in the USA.  (I have been collecting vintage broadcast receivers since 1967 and this is my first discovery of the method.)

I plan to exhibit this radio with my TGK-3 thermoelectric generator at vintage radio conferences here and consider any information about the making of these welded connections of great importance.  I would like to know what kind of tools were used (I presume it was some sort of hand held electric arc tool.)   And also why the connections were welded and not simply made with tin/lead solder?  Any photos would be very much appreciated.

If you do not have any direct information, is it possible that you could post a query on Russian or former USSR bulletin boards for vintage radio enthusiasts?  I have no skills in Slavic languages but do know how to use Google Translate and to perform OCR on documents.  So hopefully I would not have to burden you with translations.

Any assistance in this matter would be greatly appreciated.

Yours,
Robert
