I know this may be a trivial question, but can you guide me to the right type to use? I am still learning these things and really don't know what ones you're recommending.

Thank you :)

Use the same basic type as you use for the capacitors C4,5,6. It is not a big issue in any case, but the more compact ones are also more robust, the disc type chips rather easily. On the down side the compact (multilayer) capacitors have a higher inductance than the disc capacitors, but that is definitely not an issue at the frequencies in this circuit.

Thank you, Guido. Would this one here be a better choice:

These are 0.1 uf 100 volt, epoxy coated, radial leaded multi-layer ceramic capacitors.

thank you for your guidance!
