Hear both sides of tape on playback ??
It's a 4-head reversable deck where the Forward tracks are arranged across the physical tape surface, front-to-back as follows:
ForwardLeft ReverseRight ForwardRight ReverseLeft
...so it sounds like the Reverse playback heads are engaged at the same time you play Forward, so you would hear those adjacent tracks backward. If you play the tape in the Reverse direction, is the Forward program audible (but backward)?
If so and in otherwise high fidelity, something in the Forward/Reverse head selection may be hosed.
Or, if the out-of-phase tracks are mushy and low volume, the physical tracking of the tape across the heads could be WA-A-A-A-Y bad. That would probably be visible as sideways distortion in the tape path. Shine a high-intensity light on the tape where is passes over the heads, then reverse it while watching where it sets up on the heads. It should be centered on the heads and not change its orientation when reversed. Compare where it tracks in motion with the probable visible wear marks (shiny bars across the heads perpendicular to the travel) where the tape has polished the heads over the years.
Or, the heads are so worn the coils pick up signals from their neighboring tracks.
