Power Supply section?

Hi, if I have two circuits, how do I have to do it to join them in the power supply section? I attach the images as an example, if someone can help me.
Thanks

Hi
Do you want to build 2 pedals in 1 enclosure?
You need to create a separate power filter for each circuit.
In fact, the simplest option would be to connect 2 resistors of 100 ohms
From each resistor, the power will flow into its circuit.

Hi, thanks for responding, so you say I should keep filtering on each one? and only with a resistance one the power sections? I hope to understand well

In fact, it is necessary to add a 100 ohm resistor before the capacitor 100uf
from a wire of 9 volts the current will be pumped to 2 resistors. From the first resistor, the current goes to the chorus, from the second resistor to the distortion.
In the distortion, the diode 1N4001 must be set as in the chorus scheme, between power and ground
this is how a resistor should be installed

What's the point of mentioning dc resistance at the input of the power section? They are present here simply for reverse polarity protection (they burn of overcurrent instead of parallel connected diode).
