Thanks for the tips. I already found them on rs-components (and I have 
contacts who can order there). But aren't tantalum cap's polarised? Or is the 
mic signal DC? Or is there another reason why this isn't a problem?

My coursebook states that they can withstand voltage reversal. I interpreted 
this line as: they're not designed for it, but if you do it once by accident, 
they won't break.
