Well it's been twelve years since I worked on a vcr, but back then it was
not
difficult to get to the wiring (actually posts). You would unsolder the
post from the pcb on top of the head ass'y, remove the screws and lift the
head
ass'y off the rotary transformer ass'y.
BTW where did you look it up at?

Google took me to the wikipedia. I've got an old 4-head VCR that doesn't
work any more. I think I'll dig it out and take a look. Thanks.
