Greetings from Canada, My Saba 300 has a problem with the automatic tuning. It works normally in search and fast mode in both directions, except it won't stop in one direction when it tunes in a station on MW/Broadcast band. FM works normally in both directions. I have cleaned and checked the control switches and they appear good. All capacitors are new. A new ECL80 and EABC80 does not cure this. The AM output from the control transformer appears the same in either direction. I have checked the alignment of the transformer. The translation by Google from German is awful and I can't understand much of it. Has anyone had this problem and can help? Regards, Gary

Hi Gary, Since the FM search tune is working fine, one would suspect a problem with the MW Control Transformer alignment. My experience has been that the IF strip alignment and control transformer alignment interract and the best results are obtained by exciting the ECH81 grid (pin 2) with a RF sweep generator set to 460KHZ with a 20-30 KHZ sweep and then looking at the IF curve (top of R23) and control transformer curve (Point P) using a scope. Get the two curves lined up together and make sure the frequency discriminator output (Point M) is symmetrical around the peaks of the IF and Control Transformer curves. You may also want to double check (using an ohm meter) all the search tune switch contacts. Also, verify that the 60HZ drive signal amplitude on Pin 9 of the ECL80 is the same in up and down search for both fast and slow tuning. Also, verify the value of the 18K braking resistor, R103. Also, verify that the coupling adjustment (taped over hole on Control Transformer) has not been tampered with. Hope this helps. Thes radios can be a little finicky to tune up precisely. Regards,
Kirk |

1 Hi all....Thanks for finding my radio! I had a question about the small bulbs under each pushbutton. How do I get to them? And Will I be able to find replacement? The electronic tuner litters and shakes after tuning a station....Is this normal? Thanks AL |

Hi Alfred, If you need information about the automatic, you can find it here (its in German, may be google language tools can be a help to understand it). There are more articles in german about saba specific repairs, many of them you will find with "suchlauf" (German syn. for automatic) in the general search. Most information (in German) at Freiburg 125. Don't try to remove the buttons, you have to remove the chassis to change the bulbs from downside. Best regards Martin |

Hi all....It seems the jittering of the electric tuner was caused by a weak 6AB4 tube. I guess it jittered because it was trying to tune in station. Now it works perfectly. I noticed there is a empty tube socket on chassis. On the tube diagram it reads 'Multiplex'......What is multiplex? Thanks AL |

Hi Alfred, the mentioned socket isn't reserved for another tube... There one can install a multiplex-decoder. Essential for rf-stereophonic listening. By the way: your radio seems to be a very early model which has the facility for later upgrading to rf stereo reception. The right decoder should be this one. Nowadays difficult to acquire... Best regards, Bernhard |

That would be the optional install to receive stereo signals. Being that the radio is from the early sixties, many buyers of these radios weren't sure if they wanted to fork out the extra bucks, or deal with the early/primitive multiplex units. Some eventually did place the multiplex add on a few years later. |
