    Hi guys,
    I want to make a graphic EQ for my amp, and I want to replace inductors with gyrators, but I need some help:
    1.Is the transistor emitter bias resistor fine(6.8K), or I should use another value?
    2.Do I need to use dual voltage supply for the circuit?
    3.Are the Q-point feedback resistors (100R) OK, How to determine them?

    Here's my schematic:

    Thanks.
