Figure 2. Cascaded pots showing parasitic capacitance. On the left are two terminals labeled input. The lower one connects to the ground line which is connected to the chassis. The upper input terminal connects to the top end of a pot that is labeled 500 k ohm. The bottom of the pot connects to ground. The wiper connects to one end of a capacitor that is shown in red. The other end of this capacitor is grounded. The capacitor is labeled 65 p f. The wiper of the first pot also connects to the top of a second pot that is labeled 500 k ohms. The bottom of the second pot is grounded. The wiper of the second pot connects to a second capacitor that is shown in red. The other end of this capacitor is grounded. The capacitor is labeled 100 p f. The wiper also connects to the top output terminal which is shown on the right. The other output terminal is grounded. A note on the diagram says quote, both pots are set to one half attenuation. End quote. End verbal description.
