Ceramic capacitors. Re-thinking them.

[CheapPedalCollector]

How do you determine the level of humidity in the caps?

They start to be really noisy and make spitting sounds and a lot of white noise. I mostly run across it in old amps, but the occasional pedal. My Distortion + had one like that.

Have you tried drying them with a heat gun?
Weird that the heat from the components in the old amp didn't keep moisture away.

Heat (by itself) doesn't dissipate moisture..
(dry air circulation does..)

I noticed this while cooking jerky with a fan.
Also during the recap of old amplifiers with dried electrolytes.
