Here's a the schematic of the venerable Kenwood M2a power amplifier. Th amp in my opinion has a lot of potential and seems to have a decent front end.

I'd like to upgrade some of the components.

PLease look at c9 and c11, can these be replaced with Metallized polyproylenes? I hate to have old lytics in the signal path... What do you experts think?
