Possibly to put your fags and matches on when you are listening to music. My Marantz amp doesn't have them on.

I will get to find out. I have read on other forums about the covers and people say that their amplifier has them on but nobody can give an explanation as to what purpose they serve.

Damping plates to stop the crappy build case work from rattling...

I'm not surprised that you're curious.
That top one looks like something someone might have used as a base to take a smaller component on top.
(With the intention to block rising heat 🤔)

Seem to remember seeing similar on this forum - there must be some good reason.
Mysterious......

Never seen these on the Marantz amps I've owned (3).

Nor any of mine suggesting they are after-market fittings.

My pm6006 has one. You can clearly see one on the image of pm6007 in the review on this site. No idea what it is for.

My Yamaha AV receiver has one. Always wondered why

 

[SteveH72]

I believe it’s something to do with European fire hazard safety regulations. God knows how it helps, though.

As does my old Denon DRA-F101😜

Now that one is just silly, it's covering most of the vents.

Good old Europe 🙄
They're the reason for stoppers in the 4mm terminal posts too.

Candles and vases full of water found their way into old style TV sets - but these partial covers wouldn't prevent such ingress....

This is one of the reasons I don't get what they are for, the plastic sheet has all the vents cut in it too. 🤷

Glad im not the only one ! they have been baffling me for years ..very odd.I noticed they are always on the input switch side on all Brands.

If vented this would tend to support the damping plate theory...
