Stereo decoder for SABA Freudestad 11-Stereo?

      Hello to everyone,

      I need an advice. I have SABA Freudestad 11-Stereo radio that sounds beautiful (all Siemens tubes) but it's not stereo, althought has "stereo" in the name. I consider to buy and instal to it a stereo tube decoder from another tube radio (Grundig?). Do you think will it be work? Is it possible? I wonder if someone has done it before and can share about own experience, especially how to estimate a proper stereo-decoder to Freudestad 11-Stereo.

      Best regars,

      Hi Renes,

      usually the Freudenstadt 11 has only stereo at the TA-Exit.
      It's not prepared for UKW Stereo. Only the Saba's from 1964 (and the further generations) are prepared für UKW-Stereo (for example Freudenstadt 14, Freiburg 14, Freudenstadt 15, Freiburg 15 and some more).

      But you can built in a Stereo Decoder (for example a Saba E16-Stereo Decoder).
      Sometimes the are some at eBay.
      I know that it is possible to built in one, but I don't know how. ;)


      Best regards,

      Hello renes

      It is my belief that the "export" (to North America) version of the Freudenstadt 11 is the SABA model 200 (1961-62).
      This model, as well as the export versions of the Meersburg 11 and Freiburg 11, was equipped with a stereo decoder specially designed for SABA by the "Fisher" Corporation (USA)
      Three tubes (1 x ECF80 2 x ECC83)
      (This is from my poor memory..Please correct me if I am wrong....)

      A recent auction from the U.S.A. shows one example with tube decoder:
      http://www.ebay.com/itm/VINTAGE-SABA-200-STEREO-TUBE-RADIO-HI-FI-AM-FM-MARINE-SHORT-WAVE-GERMAN-/260898735407?pt=LH_DefaultDomain_0&hash=item3cbec6c52f

      I have a Freiburg 11 (German domestic version) that I have converted the UKW tuning to full spectrum tuning (-108mhz) and modified the automatic tuning brake circuit, motor capacitors for 60 hz operation, etc.

      I hope to find an original FISHER decoder for my Freiburg 11, but the chances are slim at best.
      However- if non-originality is OK for you, there is an easy, low-cost alternative from Germany.

      From the company "KEMO" is offered Nr. B 127, the Bausaetze + Module
      stereo decoder kit in solid-state form.
      The cost was < 10 USD at the time I purchased some a few years ago, but I had to place a minimum order with the U.S.A. seller MCM Electronics in order for them to place a wholesale order with KEMO.
      Here is just one German seller:

      ...and a description from KEMO in English....

      Enjoy your fine radio!

      Hi Achim!

      I *think* the early export UKW stereo SABA models used a version of the Fisher MPX-75. (per RMorg, Karl Schmitz)

      Having worked on only a rare few of these tube-type MPX receivers so many years ago, so I have little first-hand expertise for them.

      The Grundig single tube reflex decoders are indeed ingenious.
      Still trying here to fully understand the circuitry for them.

      I have had too much joy becoming somewhat familiar with repairing only two the infamous SABA E-14 transistorized decoders.
      The AF11* transistors pose a lot of trouble in their old age!

      Kind Regards-
