Since heat rises it would help to have some way for some of the heat to escape through the top plate.
It looks like there are two holes towards the sides that have a screw or bolt that are not really doing anything. As an experiment you could try to remove them to see if it helps.
It's a lovely looking piece of equipment but I would be tempted to drill some holes in inconspicuous places.

I will give that a try, plus I am going to install a small 40mm fan with a variable speed. It's been on all week during the day despite the heat and sounds great, zero hum, deep soundstage.
As far as changing the design, i.e. components, I will leave that to someone more qualified in the future.
Thanks for all the comments and help.

If you have failed components, you should have it fixed.
