Accurate Low Amp Current Probe Advice

Personally I rather leave components which work OK alone. Whatever you take apart is not getting better; only thing you can do is try to minimise damage. ;) In Dutch we have a saying which kind of translates to 'repair it until broken' (which is not a good thing).

I am with you, never touch a running system - normally.
We (the company) consistently replace electrolytic capacitors after 10 years in the device to ensure continued operational reliability.
However, these are also stressed accordingly.
Electrolytic capacitors dry out over time, faster or slower depending on the load/ambient temperature.
That's why I suggested taking the appropriate measurements.

If it worked ok, I would have left it alone. 😉
It went from 4.5mV PP to 0.2mV PP. I'd call that an improvement. I like stability.

This is why I went after those caps in ~37 year old device.

The date codes on various seem to suggest your unit was manufactered after 1995. What date does it say on the 'tested' sticker? Interestingly, I'm using the same stickers BTW.
