Hey Todd, I've never heard of power supplies degrading. That is pretty interesting. I may have to try that if I can ever suspect that a power supply is causing interference noise, etc.
how would you measure if a power supply is doing this? Can you use a scope and look at the supply voltage, etc. ? Or do you just replace it and if it goes away, then you fixed it?
