[QUOTE="Reg, post: 183092, member: 3659"] The specific design of the audio is different on the SPP and SL than it is on the TDI so adding a tone control would be a real challenge on the smaller units. Personally, I wouldn't even try to do it. On the TDI, an internal tone control exists. Vr3 is the internal audio tone control that sets the tone and it is located near U5. One could add an external tone control by modifying the existing design but to be honest, I can't tell anyone what would be the best values of components. or exactly how to do it. U5 is an AD654 which is a voltage controlled oscillator. Reg [/QUOTE]
