@jerzone Don't know if you still have your Onkyo around... this is a different model but they seem to suffer wonky capacitor syndrome🙄

Fixing An Onkyo Receiver With Multiple Faults
Modern-day receivers are miracles of digital audio and video processing, but compared to their more analog brethren, they can come with a host of new and fascinating faults. The Onkyo TX-SA806 and …

@lfisk For some reason (probably a friend that moved) I have two Onkyo's, but we are using a new Sony.
Caps seem to be the first thing to replace when t-shooting. When I was in the AF I put a 'scope on the power supplies of tower electronics and they were all in need of new caps. -

@lfisk Radio station I worked at in the 70's had an automation system with a huge drawer of power supplies below the computer boards. No idea what the DC out of that looked like, but the heat coming off of it was blazing and it just cooked all of the (socketed) chips on the boards above it.
Also the whole system was super sensitive to any kind of static electricity, we'd regularly spray fabric softener on all of the carpet surrounding it. You don't really see that these days, seems like they figured out grounding and shielding or chips are more robust. -

Carried my own 14 inch fan. A lot easier to trouble shoot stuff when you don't have sweat running down your face
We had a LOT less calls at sites with air conditioning. Just an exhaust fan was a big help.
Suspect a lot of the stuff made today for use around offices and such has built in anti-static properties. I've noticed or rather haven't noticed getting zaps while moving about them like years ago. Also think you're correct in that they keep static in mind during design nowadays too
