I have a Sony VCR model SLV-EZ8 which is about 6 years old. Its a 6 head hi-fi unit. Recently, the sound on recordings made with the unit, have a strong phasing effect during playback. It seems to be worse until it tracks and at times the phasing is only slight but there is an obvious effect - kind of like what you can achieve with parametric eq. I opened it up and played around with the alignment of what I think is the sound heads and I can make the problem lessen but not disappear unless I screw them down far enough to make the alignment so bad that the signal turns mono. Then the phasing and parametric eq effect TOTALLY disappear. I suppose 'natural' phasing is a stereo effect?
Does this sound like an alignment issue or could the sound heads be worn? Anyone got any suggestions before I fork out the caaaash for a pro to look at it?
Thanks in advance.
