Can I use a higher voltage rating when replacing capacitors?

Replacing a capacitor with something that has a higher voltage rating is always safe. The only problem there is that a capacitor rated for a higher voltage is often physically larger, everything else being equal. Make sure they actually fit in the same space. Sometimes it is also safe to use capacitors with a larger capacitance (Farads).

Ceramic capacitors. These capacitors use a ceramic dielectric. There are two classes of ceramic capacitors, Class 1 and Class 2. Class 1 is based on para-electric ceramics like titanium dioxide. Ceramic capacitors in this class have a high level of stability, good temperature coefficient of capacitance, and low loss.

Can you replace electrolytic capacitors with tantalum ones?

The zobel capacitor can be ceramic or nylon. C7 probably you can''t find any of this value 0.1uF but you can change it to 1.0uF this will give some aditional bass to your amplifier; however if you use any ceramic capacitor won''t have any problem. I''ve have made this preamplifiers for my projects with success handling tones for hifi amplifiers.

Ceramic vs. Film Capacitor: Which one is preferred in audio circuits?

"Film Capacitor" typically denotes polyester or polymer film as the dielectric - as another answer points out, metallized film capacitors are the same thing: A metallic coating being applied to an extremely thin polymer film, to create the conducting electrodes of the capacitor. In general, ceramic capacitors are somewhat non-linear in their frequency …
