I recently picked up a "VICTOR COMPANY OF JAPAN"; MODEL TH-2770; SERIAL 3914 and am looking for a schematic, service manual, photofact or anything to help with repair.
I noticed that the picture I attached shows 2 coils on the AM ferrite antenna......my radio only has one coil and it appears that the ferrite rod was repaired at some time so the AM antenna may be the problem??
When listening to shortwave, I got reasonable reception using an 100' external long wire antenna clipped to the telescopic antenna. The built in telescopic antenna didn't seem to work very well, even on strong signals, maybe there is an issue there also?
I have attached a couple of pictures to help with identification of the radio and the link to the Radio Museum where the specifications can be found.

Any suggested info sources would be greatly appreciated.
