If I want to play around with the values of the R C combination ( usually 0,002µF and 150k ) in front of V2 (which is last 1/2 ECC83 before the phase inverter) what is the best procedure?
Do R and C influence each other or do I just change C for sound and R for gain?
Thanks

That R and C are interactive. The R has a dual role; it is part of a voltage divider that determines how much oomph goes into that V2.
The R and C together are a high pass filter. Do a search on web and you'll find a high pass filter calculator. Plug in the current values and see where the cutoff freq is. If you want to increase/decrease the R for gain, you can find out what C you need to get the same high pass effect.
