Unfortunately, I can't find the blog any more.... I found it in a blog where they were saying that they kept the part of the chassis containing the power transformer and the two output tubes to come up with an active speaker. In this blog there were other pics of Freiburgs. Yes, according to the details you guys point out, it is photoshop.... How nice it would be to build a pair of amplified satelite speakers like this for the radio!

Dieter! I wish I could find out who made it. Yes, there should be one knob available in somebody's drawer

I found this interesting picture of a modified Saba Freiburg 11. The cabinet has been cut to fit the power amplifier and the power supply only. It became now an amplified loudspeaker. Nice to build two of these as satelite speakers for the radio! A lot of work, and high woodwork skills are required though. What do you think about this idea? Interesting to know your thoughts.... We need to think that this person "destroyed" on radio to build this loudspeaker! 2231644658_d636fca6e5_b.jpg%22

Excellent Dieter, we'll be in touch. Ah... How much I would like to have the remote now after your description

Thanks a lot Peter for your help! I've been checking after your link the other spares that can be found on eBay Germany for these radios... Amazing! Almost everything is there! I wish I lived there to buy the remote control (absolutely unknown here) and the back cover too... If any of you is planning a vacation in South America, you are welcome to visit me for a tea and cookies or a nice dinner if you come with the remote control hehehe!

I adjusted the discriminator. It works much better. AM stops in every single station left and right, and the auto tuning is stopping exactly where it should, in the center of the carrier of each station. The strenght of the dial knob against my hand when I try to move it away from the tuned station is very high. FM same thing, except that still it does not stop in every single station to the right but it is much better than before the adjustments. I should keep trying to adjust the stop screw, I…

Yes, the first one is tapped... I will check the thread and be extremely precautious when touching any of the adjustments. There is still a small problem: In FM, when searching to the left it works great, and when searching to the right it skips some stations that were detected when looking to the left. Someone in 2010 had the same problem, but unfortunately there were no answers on the thread: foundcollection.com/2_b41c7d52917760a0_1.htm Thanks a lot Dieter! I will never stop saying that I ADMI…

Dieter, It seems like years and years of connecting and disconnecting the motor through this switch generated sparks that were depositing slowly carbon that linked these two contacts. Do you know where I can find which hole on the discriminator holds the adjustment I should change to make the automatic tuning system stop exactly in the center of the station carrier?

Mike!!! I FIXED IT! I couldn't avoid getting into it again, that's me Please see the explanation on the old thread. Very unusual problem (at least for me): http://saba.magnetofon.de/showtopic.php?threadid=7159&pagenum=2

FIXED 100%!!!! I want to share with you what the problem was, just in case this will happen in any of your radios because it was a strange problem. Yes, I am stubborn. I looked for the service manual online of the Freiburg 11, I couldn't find it, but I found the one for the Freiburg 15. It has a very detailed description about how the automatic tuning works. I studied all that was described there, took out the chassis and started measuring and analizing. It was easier than I though, I just neede…

Peter, I tried and tried and I couldn't solve the issue. I opened a thread in english in the proper section, but nobody replied. So I quit. I spent a lot of time trying to find the problem, and also the radio is very heavy to keep moving it around. I will use it manually. Unfortunately. Thanks for everything.

Ok, I couldn not solve the issue alone with no help. I checked all the resistors around the two tubes related to the automatic tunning, everything looks ok. I had already replaced all the caps. I even replaced the cap on the chassis, the one in the can that goes to the motor. I tried another ECL80. Nothis worked. I measured all the voltages indicated in the schematics, and only one was not correct (the one in one of the grids of the penthode section in the ECL80, wich reads 90V instead of 180V b…

Ok.. time passed and things got worse. I didn't even take the chassis out of the cabinet. I was playing with the front buttons and suddenly the system stopped working. Pressing any of the 4 buttons it just goes forward, not backward any more, and it doesnt stop in any stations....

Hi all, Maybe you already saw my other thread. I replaced all the capacitors and oiled the mechanical parts of the radio. Sound and mechanics are great now. The problem is that the motorized tuning only works in FM in backwards. In forward it just skips all the stations and reaches the end of the dial. in AM it works well in both directions. Has this happened to you before? What can I check? Here is the video: https://www.youtube.com/watch?v=IzjoZ7h5j7g Thanks!

Hi Peter! Thanks a lot for the link and for the nice wishes I will check the link to see what I can find there. Guess what? It almost always happens... I finished putting the chassis back in the cabinet, I moved it from the kitchen to the living room, and guess what? There is a microphonic effect! This was not happening before.... Maybe a tube is receiving the vibrations from the motor, the sound from the speakers, and even a hit on the front glass from my finger. Strange. And also something els…

Dieter, I wanted to make a joke but it seems like language barrier and difference in cultures made me fail. I am not blaming anyone, the other way around, I am abusing posting in the german section of the forum I am now cleaning the cabinet, putting back the fragile glass (the paint is falling appart), cleaning buttons and knobs as well. One of the big knobs has the big brass ring missing, and the two small ones the two round plates missing... I wish someone around had some spare ones, they fit …

Dieter, The force of the motor against the hand movement is strong, so that is a good news. About realignment, as you say it is very critical I will skip that... I dont want to try it and leave it worst than now. At least it is working, it is ok how it works now, so I declare the restoration finished! I bought 12V and 6V small bulbs. The 12V one didnt work nicely, the 6V one worked perfectly! Same illumination than the original 8.5V. Why? Because it is 6V 55mA! They get a small current flow (onl…

Dieter, Gut, dass du mir das gesagt! Es gab einen Grund, warum der FM nicht in Mono arbeiten ..... Nach langen Stunden, die ich begonnen, für ungerade Sachen zu suchen. Es scheint wie eine vorherige Techniker geändert Verbindungen in der Stromversorgung. Ich habe alles, was nach den Originalschaltpläne und es sehr verbessert und auch der FM begonnen, auch in Mono arbeiten. Trotzdem war ich immer niedriger Spannung, so dass nach dieser Änderung ersetzte ich wieder die Gleichrichterbrücke und das …

Update.... Just in case, I replaced the rectifier diodes and the big filter capacitors. Same thing. I started playing with the buttons and I discovered that the stereo-mono switch affects the +B voltage. When in mono, the voltage on the plates of the EL84 is 250V. When in stereo, it drops to 200V and high consumption in the power supply starts. Something else, when in mono, the FM just do not work on any of the channels. Even the green tuning indicator tube receives no signal. When in stereo, th…

I bedeutet den Metalldraht, der die in der Bewegung der Antenne gemäß der Knopf, der drehbar macht beteiligten Kunststoffteile miteinander verbindet. Es ist ein kleineres Problem. Ich das Radio eingeschaltet ist! ............. Es scheint ein Problem sein. Die Spannung + B direkt nach der Gleichrichterbrücke (Punkt 1 in den Schaltplan) ist 300V, sobald ich das Radio an, und das ist, was die Schaltpläne, so soll es sein, aber es fällt auf 250V, nachdem alle Röhren warm sind. Der Gleichrichter Meta…
