What digital gear do you expect to survive a dozen years?
My N-50 still powers up and works ok.
All of mine ...
And even a dac that is over thirty years old.
The only defective digital equipment at home is modern and is stuff I got for free to salvage parts or boxes.
It booted 2 times then no boot.I am thinking of if I can get it to boot again so that I can leave it on.I can shut the display off...
Once I was repairing a SMPS which dropped output voltage a while after power up. Some while after unplugging the voltage was OK again. The culprit was a temperature-dependent voltage reference (actually the basic TL431) - when the PSU got warmer, the voltage reference started dropping output voltage. After cooling down upon power off the voltage was OK again. Sometimes electrolytic capacitors produce the same issue.
I would probably start with measuring output voltage of the power sources and monitoring what they do after cold power up. If it turns out the cause, a specific PSU can always be fixed or replaced somehow.
