"Intrepid" asked some time ago:
Does anyone have a source for complete schematics for this radio?
I've got some ideas for mods already...

The GRUNDIG FR200 seems to be equivalent to the TECSUN Green-88:

The schematic for the TECSUN Green-88 is available at Conrad

Here is the datasheet for the Sony CXA1691BM:
