This is the CCT of the pre preamp I am thinking of building, could anyone inform me what would be reasonable components to use, not values but type.
I know different types of caps etc. in certain paths alter the sound, but don't know which to use where.

The components are:

Q1 2n4401
Q2 2n4403
R1 100k
R2 330k
R3 & R4 1M
C1 0,1 microfarad
C2, C3 & C8 100 picofarad
C4, C5, C6 & C7 100microfarad
 
Maybe this can serve as inspiration. This has optic psu:)
