    That’s why they put those teeny drain plugs on PIO caps. You HAVE been changing the oil annually, right?

    I use the spent oil to style my hair.




    Maybe that's why it all fell out... :confused:

    Seriously, the oil used in old caps etc may be highly toxic.
    Modern production oil caps should be safe.

    I don’t think that they used dielectric oil with PCBs in small caps (signal coupling type) too much if at all. Mostly in power applications like transformers or big high voltage caps.

    Coupling caps are directional for outside foil, check this YouTube and build one of these testers, they allow you to determine the OF outside foil and also listen to the sound passing through each cap. The old Wima tff caps are great for cleans, mustards for dirty. VQ is a quiet cap and not the tone for a plexi or fender sound.
