Hi Matt,

Your "fat caps" have failed internally and are puffing out as they burn up
inside :-(

You can easily mix cap types as you wish.  The only concern would be if a
particular cap died and left a cap value that would go uncontrollably
resonant or something.  Good safety gaps should prevent that in any case.

Cheers,

	Terry
