i see to where you can set it to get 50 or 60 hertz so how do i make that more of a wider range? could i just use a 100k pot?
i assume that on some higher frequencys the caps would have to be changed?
Yes, you can use a larger pot value to obtain a larger range.
If you want an even larger range, then you could use a rotary switch to switch in different capacitors, ie. the switch for course tuning and the pot for fine tuning.
