That is worrying. This thing is full of components on multiple PCBs and trying to replace them all would be quite the task.
I opened up the metal TBC C.B.A box mounted on the bottom of the VCR (see attached pictures), and while I'm far from an expert, I couldn't see any bulging caps or sense any strange smells. I'll have to look into it a bit more when I have the time.
