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!

Lyrics:
Conversion, software version 7.0
Looking at life through theeyes of a tire hub
Eating seeds as a pastime activity
The toxicity of our city, of our city
New, what do you own the world?
How do you own disorder, disorder
Now, somewhere between the sacred silence, sacred silence and sleep
Somewhere between the sacred silence and sleep
Disorder, disorder, disorder
More wood for their fires, loud neighbours
Flashlight reveries caught in the headlights of a truck
Eating seeds as a pastime activity
The toxicity of our city, of our city
