I have a beginner question.
I replaced the bias filter caps in my dynaco pas with standard insulated axial caps. The capacitor bodies are touching the the chasis and the metal clamp on top of them, just like the old ones and it got me to thinking....
is it bad practice to put insulated caps in contact with chasis ground?
Is the covering on the components enough to safely install them like this?

It should work for now, but in the future the plastic cover may get loose or come off.
Then the metal case touching ground could be a possible problem. Why risk it?

I have seen it done (rarely) in commercial equipment, but it seems a poor practice to be avoided.
There does not seem to be a standard for the voltage isolation of the plastic covering, either.

It should be fine if not exposed to any vibration issue that would cause rubbing against the chassis,
like loud music. But you could always add a bead of silicon glue between the capacitor and chassis
to prevent wear and add an additional layer of insulation.
