hello I need if someone has the analog multimeter circuit (hung chang 102 BZ), it is not the big deal but it brings back many memories of the technical school, on one occasion measuring amperage broke, and does not measure AC. No amperage, all other functions are perfect, today after 25 years, looking for other things I found it saved and I discovered that it has a Germanium diode (I think), that it is fractured and I would like to know what diode it is and its characteristics to replace it , I upload photos, thank you very much any contribution would be helpful

The diode, although it looks like germanium, according to the scheme is silicon, 1N4148.

Thank you very much for the electrical scheme of the multimeter and for your contribution, it helps me a lot, it is more the scheme I printed it, and plasticized it, I will wait for it in the multimeter box, for any eventuality, I will try to get the original Germanium diode and if I do not replace it with silicon, thank you friend.
