Also if you have any mics that have there own power supply (i.e.tube
mics)
those should not have phantom power applied.

This has not been my experience. I think tube mics with their own
power supply would be completely unaffected by phantom power, and my
personal experience has born this out.

Being about the most forgetful person in the world, I am constantly
connecting tube mics and ribbon mics to preamps where the phantom
switch had been left on from previous usage. Sometimes i notice and
turn the phantom off, sometimes I don't. I've never had any problems
with either sound deterioration or microphone damage.

The real risk is if you should accidently use a miswired cable.
Sending phantom via a cable with the pins miswired is a recipe for
disaster.
