Upsizing Capacitors

Best practices: If it works, leave it alone.

People spend months or years designing amps and other people who think they know better want to "improve" on the design. Where's the facepalm emoji? Sheesh.

Measure the capacitors with a good lcr meter to see if they have degraded due to age 

Replace if they are more than 10% low. Otherwise leave them be.

I used a car analogy in another thread, have always had the same logic on auto "upgrades". Take wheels for example, somewhere you have an engineer who dedicated their LIFE to the field and maybe months/years on any specific car only to have someone think they know better - it's a valid point!

On circuit design, absolutely. What prompted my post is every other capacitor DIY story, we have people increasing capacitance! On average, more negatives than positives (pun totally intended)..

As others have mentioned you better know what you're doing if changing capacitance. I will occasionally upgrade for  temp, voltage or tolerance, this mostly in power supplies.
