I have a ribbon mic I'd like to gig with, and the PA systems we use
normally plug into have an all-channels-on/off for the phantom power.
Our vocalist uses a condenser mic, so she needs it on. If the phantom
power hits my ribbon mic, it might permanently damage the ribbon
element.

Does anyone know of a DIY homebrew solution?

Measure the resistance from pin 2 and 3 to pin 1 using an ohm meter with
limited current, such as a good DVM.. If it is infinity, you don't have
a
problem, and then stop worrying.

Of course it could have a Transformer isolated output in which case he
could
read a near short and still not have to worry ....




** You better **re-read** what Arny posted - ie test from pins " 2 and
3 to pin 1 " !!!!!!!
