The input terminal goes through a 120 k ohm resistor to the top of the Bass pot. The bottom of the pot goes through a 27 k ohm res to ground. There is a .003 mike cap from the top of the pot to its wiper. There is a .015 mike cap from the wiper to the bottom. There is a 750 pf cap from the input terminal to the top of the treble pot. There is a .0033 mike cap from the bottom of this pot to ground. The wiper of the treble pot connects to the wiper of the bass pot and this is the output point. One half of the balance control, 500 k ohm, connects from the output of the tone control to ground. The grid of the next stage would connect to the wiper of the balance control.
