saba wildbad 11..help
Hi every one
i have a SABA wildbad 11 with a problem of low sound volume specially on the AM and SW. the FM is a bit better the tubes and the caps. are replaced with new ones.
i checked the audio output transformer and the primary coils measures 525 ohms and the secondary coils the one connected to the speakers measures
0.5 ohm while the other secondary coil measures 45 ohms
does that mean that there is a short circuit on that part of the transformer
the speakers measures 5 ohms each
can anyone help me so solve that problem?
one other question is that ..what is the Si.6 stand for which is seen in the schematic on the primary side of the audio output transformer

I am doubtful that the output transformer is the problem. Usually they either work or dont. The Ohms for the windings sound OK. Also the FM is better.
So more likely loss of RF or IF gain somewhere.
Dont know what Si.6 stands for.
There are some differences between Saba Wildbad 11 and Saba Wildbad 11 Nord. The table shows the changes. Si3, Si4 Si5 and Si6 are therefore additional fuses in the "Nord" version.
thank you very much
