    I have acquired a JVC HRS7722 SVHS VCR, which is experiencing vertical bounce on tapes recorded on my other JVC SVHS decks - HRS9500 and HRS6700.
    Less problematic on 6700 recordings, but will vertically judder periodically.

    It also has occurred on recordings made on the 7722.

    Is this an alignment/tensioning issue that a service guy can sort out??? :(

    Try playing a commercially produced pre-recorded tape and report back if it still judders.

    Do you mean for a split second or two, the picture goes into half vertical resolution and shakes up and down a bit? I had that on my last JVC VCR when "Video Stabilizer" was turned on in the menu (ironic). Try turning a feature like that off?

    If it has a Time Base Corrector then try it with this turned OFF.

    Spoke with a local service shop, who suspect it to be an alignment problem either with the heads or control head. The HRS6700 which has an identical tape mechanism to the 7722, has no problem.
    I know later models featured video stabiliser but this doesn't, and it has problems with its own recordings losing vertical sync periodically.

    If it has problems with its own recordings, it's likely to be a problem with the back tension or possibly worn heads.

    If the problem were to show only on tapes recorded on other machines, the fault would probably be misalignment of the tape path.

    Thanks for that - possibly its both, but not worn heads - gives pristine clarity on its own recordings, no head related dropout, plus bought this off zAndy1 (AV Forum user) who tells me he's had about 30hrs use out of it. :smashin:
