[sdiy] ASM Capacitors/Bench Power Supplies

After looking on a few different websites it's become apparent that some of
the caps that I need in Poly-whatever only come in either Ceramic or
Silvered Mica versions.
Could Silvered-Mica caps be used instead of Poly-whatever caps or is there a
problem with how they 'operate' ?(for want of a better term).

Regards
