Im not sure as to the original question but I do know that it’s best to not stack the 8 track player on top of a vcr for best sound quality. If it’s a beta vcr then no issues. I’d recommend checking out laser disc players though as thats the next logical upgrade.
VCR in the HDTV era
Can either the auto clock or auto channel set functions of a VCR work in the HDTV era? I'm wondering if cable has any sort of backdrop signal that that VCR can use.
