Quad 909 Review?

Okay, but if 0.6 ohms is the resistance of the wire used to make the inductor then that 0.6 ohms should be at all frequencies ?

The DC resistance of the coil is constant, the AC "resistance" varies with the frequency.
If a resistance is specified it is the DC resistance.
What do you want to achieve with this?
Cut off the bass to the speaker? Do you have a subwoofer?

He wants to MOD the amp in what appears to be many ways. Some non-effective.
