Hey everyone!

Haven't posted on here for a while but I can't seem to formulate my question in such a way for Google to give me an answer so I'm turning directly to you guys. I feel like this thread is kind of spammy as it's probably gonna be short and not generate much discussion but here I go anyway.

In late 90's, early noughties VCRs (I'm looking at the JVC HR-S9700EU in particular) does the fact that the Power Supply is on the same board as all the other circuitry rather than being on a separate power board affect the image quality in a noticeable way? I remember hearing that when it's on the same board the AC line generates more interference compared to a VCR where the high voltage part is in a metal shield on a separate board.

I'm attaching a pretty low-res screenshot of the internals of that VCR to illustrate what I mean, notice the PSU on the right on the same board and with no shielding (on a side note it seems like a bit of a shock hazard ).

Thanks for reading and again sorry for the sort of needless thread, I'm sure that with a bit more digging I'd be able to find the answer but it's getting late and I'm pretty tired.

But yes, some models of decks are infamous for noise leeching into the unit. You also see a lot of that with units that have fans, must be modified in some cases. Electrical interference noise is a problem in general for video.
