I think we discussed this - depends on how much magnetic energy storage you want for headroom. The custom dual balanced 600VA class EI core choke I have is 11lbs 5oz. The size and weight comes mostly from requirement of 14ga wire and 60mH with 0.5ohm DCR.

Impedance sweep (two separate ones line up) and fairly linear behavior from 20Hz to 20kHz.

I am told that the 60mH and DCR spec of 0.5ohms is at 10kHz.

Oups, yes, you're right. I forgot that series or parallel windings act different when they're on the same core. I guess the Lundahl is out.
