I haven't heard of one. The receiver has been around since 1987 so I
would assume that stories of R5000 receivers burning up from "super
heat" would be all over the net by now. How many failures have you
read of that are traceable to overheating. Indeed how many of those
receivers have failed for any reason. Not many in my experience.

Dont know either, but I know mine ran HOT. And just for the lost energy
alone it was enough for me to decide and buy an external 13,8v supply.
Now I can safely put something on top of the rx again (like a logbook or
guide) without having to worry about all that heat...

And I've owned stereos that put out some heat but ran for years. The
real question is whether Kenwood engineers considered the heat in the
radio design. Given the radio's excellent design, high performance
and record of reliability I suspect they did. The radio was well
vented so the heat was dissipated.

And that excellent design, did it extend to the stock wide AM filter?

LOL.

If the part normally runs so hot it will burn fingers, that's too hot!
And that's with the case off. I've never had a stereo amp or receiver
that ran as hot as both my R5000's did, and I've had a lot of equipment
over the 40+ years since I bought my first stereo receiver in 1966.
