Head switching noise different between VCRs?

[mjg8729]

So I’m finally getting around to doing transfers using a JVC SR-V10U refurbed by lordsmurf and ATI 600 USB. I’ve previously done DV transfers about 10 years ago with a standard JVC deck. When comparing the old captures, I’ve noticed the new JVC has some considerable head switching noise vs the old run of the mill JVC deck. Is there any solution to this at all? I have attached a particularly bad example where the noise is quite aggressive. I also feel like there’s somehow more detail on the older capture

The switch point is probably set incorrectly, Some had succes changine the switch point by slightly loosening the two screws holding the drum motor stator and gently twist the stator clockwise or conter clock wise whichever direction gives you less head switch, If doing it while the VCR playing a tape becareful not to drop anything on the drum.

Sorry I’m not that familiar with all the terms. What would be the drum motor stator here?

The green PCB on top with large two screws in the center.

Thanks SO much, this actually worked, just a slight counterclockwise turn and the noise is completely gone. Now if only I had compared and asked before transferring 16 hours of video 😅

That's what forums like this are for, Don't be shy to ask.

I made a short video a while back about how to reduce or eliminate the head switch by resetting the drum motor stator but never got around posting it, I will put it up on my YT channel soon.

Please do, and let me know when it's up.

The video is up.

Changing the switch point from the set factory one is not recommended, Because what it would do is play other tapes with HiFi buzz or worse head switch noise, If one wants to do this for each tape for best playback results that's fine but be aware that this will wear out the drum motor stator PCB and screws, so keep that in mind.

If the factory alignment is lost then do the procedure in the video on a good pre-recorded tape with HiFi audio.

Also only use this method if you can't adjust it via the factory procedure. On the JVCs you need the unobtainium service remote for that but on most other VCRs you don't, usually there is either a trimpot or key combination or similar for it. (Though there are cases where the electronical adjustment is very limited, like on newer Panasonic VCRs so you may need to use this method anyhow to bring it closer.)
