wrong with the feedback path of this circuit, so i'm wondering --
- if there's a way to wire up the resonance pot wrong?
- if the pinout of the 2N2222 varies with package?
- what the resistance to ground should be at various points - i'm
seeing 3.7k between the wiper of the resonance point and ground.
seems a touch low... the 1k resistor in the path raises this to 4.7k.
i'd like to get this in the rack and mangling stuff -- any help appreciated!
