Hi Sanyo owners/ admirers. I just purchased a 1979 Sanyo M9994 boombox. Just got the tape deck all back and running perfect with new belts (4), cleaning, lube, and speed increase adjusted on motor in deck. The AM tuner is fine and aligned with pointer/ broadcasts on scale, but FM portion is off across the whole scale from 88 up to 108.
It picks up all the stations fine with stereo light coming on in super strong FM local stations but it off all the pretty much equally up scale. Example: 88.5FM is broadcast at pointer pointing at 90 on scale, 96.1 FM at 98 on scale, 105.7FM at 108. The pointer cannot and didn't move on string. It has a small amount of glue on it, and reference point at beginning of scale below 88 the pointer lines up perfect. The service manual stated that is a reference point for tuner pointer to start. I suppose an alignment is in order for tuner? RF alignment? Please assist. Love this lone Sanyo among my full collection Of Panasonic and one JVC M70 boomboxes. Thanks!
