Okay I just ripped apart my vcr to find a hall effect device. I was told one was inside the rotary motor but I cannot get that apart so I think I found the other one but I'm not sure it looks like other ones I've seen a small black box with three leads coming out of the bottom but what threw me was there is a small black half circle (half orb) coming out of the back it was encased in a small metal cover that I removed. Does it sound like I have the right thing?
