Power Transformer for Saba Freiburg 14. Help please.

Hello from Australia.

Sorry for not writing this message in German. I have an old Saba Freiburg14 which has given me a few issues lately. My trusted repair man is telling me that I need a new Power Transformer. I am tarying to find a suitable replacement transformer locally to avoid paying the very high shipping costs from Europe. Can anyone tell me what are the specifications a replacement transformer should have to match the orignial one? or would you advise me to try to find an original spare transformer? in the latter case, do you know where I can find an original transformer for my radio? I see that Saba radio power transformers are available on eBay but for other models. Can anybody tell me which Saba models use a power transformer that would suit the Freiburg 14?

Any help/pointers would be much appreciated.

Thank you,
Marc
