Sony AV-3400 / AVC-3400 service manual

[Radioiron]

I acquired a Sony AV-3400 Portapac System. It didn't have a power supply so I had to build one. I eventually got It working pretty well, but lately its gotten very wonky. The image in the camera viewfinder is compressed vertically and the playback from the tape isn't that great and has some problems with horizontal streaks through the image.
I was going to put it on the bench and start with the camera and adjust it back to specs and make sure it doesn't have any component problems, but unfortunately none of the pots are labeled with what they control. Would anyone have the schematic or service manual for the camera and VTR?
