Compare the two schematics and you'll find your answer.


don't go too low with the new value though, it can be hard on the power supply when the clarifier is cranked all the way one way.


the biggest limitation to swing range you'll find is the crystal itself.

the load capacitance has a lot to do with how much you can "bend" it.

that's why the 2000's with the big crystals slide so much further than something like the grant or madison which is the same chassis but with the smaller, different crystal.


you can also try playing with different varactors.

there are many that have been tried and i can't even remember some of the names but the NTE612 used to be popular iirc.
