I has been lucky enough to find a friend that have same model with original schematics still glued inside.

He has taken a picture of original schematic and sended it to me.

I compared it with my schematic redrawed manually from SHARP model UW-122 to match the UC-103 and I found both are identical, only in my schematics I identified audio output tube as 30C5 instead the correct 35C5, also added one line from the word earphone to the switch earphone-speaker, and added fuse value of 0,5A.

The second schematic uploaded are the most accurate, use it.

Regards.

After some models readings on the radio museum list I found a very similar radio from SHARP, the model UW-122.

It is almost identical with some differences on the mains and some components:

- Cathode resistance of 120ohms instead of 150ohms on the UC-103

- Output audio tube 30A5 instead of 30C5 on the UC-103

Changes are documented and I have drawn and upload a new schematics for the UC-103 in the model list.

Hope this help in the future.

Regards.

I recently won an auction and now own this radio Sharp UC-103.

In the Radiomuseum list appear this radio but not schematics are present, with only one owner, Peter Spies.

In one of the photos I can see some documents glued to inside upper cabinet, so, I beg to Peter Spies if he can take a photo of those documents, because one of them is the schematics.

Y become veru grateful to Peter.

Thanks and regards.
