Ah, yes! Air-core chokes. Such exquisite linearity!For a typical solid-state power amp output stage one might need somthing in the range of 10 to 30 mH. A big iron-core choke of that value might have 0.1 or 0.2 ohms DCR, but an air core would have ten times (!) as much.
But with 3-phase power, we would only need 0.3 to 1.0 mH. It would be easy to use an air-core choke of that value and keep the DCR down to low levels.
The only problem is our potential customer base of people that live at the Sheraton Gateway in Los Angeles. That's a pretty small customer base. So I have an even better idea. Let's make a line of electronics that runs directly off of DC. We can sell them to people that have solar panels on their roofs. It would be easy to run +/- 40 VDC lines to the stereo system, plus we would have a bigger customer base to sell to.
We can call our new company "Jo-Hansen". Whaddya say?
