Hello from England! I am very glad to find a Saba forum, and hope the group can help us with a restoration problem on a Freiburg Automatic 6-3D.
I acquired this beautiful Saba in about 1998 from friends in Böblingen. Since that time it has been in the roof of my Parent's house. A few weeks ago my Father started to restore the radio. Here is the status now...
a) The output transformer has been replaced (Hammond 125E).
b) Output stage,including feedback and both tone controls, working well. Very clear undistorted sound.
c) All significant capacitors replaced as have some high value resistors.
d) EL84 x 2 , ECC83 x 1, ECL80 x 1 and EABC80 x 1 have been replaced.
e) Selenium rectifier remade using 1N4007s, and 100R dropper introduced into HT+. Voltages a trifle low albeit ECC83 first triode anode is high but within operational limits.
f) Auto tuning operational but giving weird speaker noise when dropping out to manual mode.
g) Stations heard on all bands including FM without external aerial.
The status is looking good right now - except for one piece of trouble. A tuning drive cord has just broken. My father has this to say...
"
The heap has unstringed itself in as much as there is a shaft connecting the tuning knob with the motor via a clutch? On that shaft there is a small pulley around whch there should be string which goes to a much larger pulley via another small pulley.The large pulley is located behind the 'auto on/off light' and drives the vhf gubbins. String just snapped as it was tuning so my guess is that its most likely perished.
All other strings/wires ok.
To fix -it needs 1) Brain
2) Thin fingers
3) Eyes
4) Any help from net i.e
Radio Museum
"
I have asked him to take some pictures. We would both be extremely grateful if anybody can provide diagrams or photographs of this cord arrangement so that we can correctly replace the cord.
This is the first Saba either of us has seen. We have nicknamed it "The Monster"
I will try to send some photographs later.
Many thanks,
Richard
