The power transformer is really interesting too. I have an itentical one from another VCR I took apart a while ago. I actually lied in the title! There are a couple SMD resistors and or capacitors in one of the metal HF cans. The VCR was made in 1987 and is a Panasonic AG-6200.
Hope you enjoyed! Sorry it is so long! I tried to keep it short but I had a lot to say cause there was a lot of stuff in the VCR to talk about!
