Can hear crackling or spitting sound when selecting HI-FI
The "crackling" sound you describe sounds suspiciously like mis-tracking. That is: The result of the Hi-Fi heads (which are on the rotating video headwheel or drum) not exactly following the recorded tracks. Have you tried adjusting the tracking slightly? The reason this happens is that the Hi-Fi tracks are MUCH narrower than the thinnest video track (used for 6 hours per T120 tape). Tape stretches and shrinks as it ages. Video recorders wear with normal use in such a way that the tracking changes.
The problem is often worse with tapes recorded at the SLP (6 hour) speed because the servo cannot correct errors as fast when the tape is moving slowly (on some machines only). Tape quality also counts...and manufacturers change their formulations without public notice. All these things can lead to "archived" tapes being lost. Solution: Use the best quality tape you can afford, not the cheapest; record at the highest possible speed. Store the tape carefully. Never use a cheap "rewinder" because they can over-tighten the tape causing wrinkles, stretches, and
other kinds of damage.
