Added AC line chokes inside CD changer...

From other experiments I know each CD changer I own adds about '700' noise to the AC line. *the noise tester runs from 000 to 999 for testing audio AC lines. The average PS Audio noise Sniffer can eat up about 150 to 200. just for an example.  
I decided to add a pair of chokes to the AC wiring inside the CD changer (plenty of space) I had on hand a pair of MIller 5502 chokes left over from a Magnepan tweak. I put one on the hot, one on the neutral.  So they look sturdy enough to be used for 120v.  
The thing is, the incoming AC voltage is only 60v/60v balanced (technical) power anyway.Stuck them in sloppy soldering and all. Wrapped the leads up with Teflon tape...Sound is slightly smoother with ten minutes of listening..Sadly I do NOT have the tester noise sniffer handy to see what they did to lower the noise exiting the player...Now f I can only find the 5520 chokes I never used.. They seem to be lost.. (so I can do the other changer I use. I was going to use the 5520 in the first place. but as I wrote, they have vanished into the wilds of my junk piles.

Surprised you didn't use the snap on versions. :)

 Elizabeth! 👍Sounds like an innovative idea; installing them on the inside. I'm always looking to place everything outside, cluttering the back of my A/V rack.
Especially if you've got the space inside the component.
I'm going to keep that in mind.
5502s work well.

This Corcom filter sound like better idea. It is basically a common mode choke.   When you wind two wires, hot and return, on the toroidal core it becomes common mode choke.  Such choke presents inductance for common mode signals and no inductance for normal mode signals.  It is because in normal mode current flows in both wires in opposite directions and each wire induces magnetic flux in the core in opposite direction.  Magnetic fluxes cancel and choke has no inductance.  For common mode signals induced electrical noise current is the same in both wires, fluxes add up, and choke presents inductance (hence reactive impedance).  The other advantage is that for normal mode (differential) currents choke will never get saturated, since induced magnetic flux is zero.

You can also make simple common mode choke by winding few turns of power cord on large toroidal ferrite.
Corcoms are nice too, from what I've read, the "R" series work really well.

You have the idea generally correct, but your terminology is all wrong. The inductance of the choke is a constant. 
@ sleepwalker65

Inductance of common mode choke is not constant. It has inductance for common mode signals and no inductance for normal mode signals.

You are confusing inductance with inductive reactance. 
How can you get inductive reactance without inductance or how you can have inductance when inductive reactance is zero.  Common mode choke inductance measured in normal mode configuration will be zero or close to zero.  That is pretty much how bifilar resistors are built (same principal) - they impose inductance in common mode but no inductance in the differential/normal mode.  It can be easily proven either for common mode mode choke or bifilar resistor by measuring inductance.

Inductors are measured in Henrys. (picoHenrys, nanoHenrys, microHenrys, milliHenrys etc... that is the voltage produced by the instantaneous rate of change in current through a circuit with respect to time. The rate of change of current flow is measured in amperes per second, which is frequency. Put another way, X(L)=2(Pi)(f)L or L=X(L)/(2(Pi)(f)). Inductance (L, measured in Henrys) of the inductor and Pi are constants. Inductive reactance (Z, measured in ohms) is the dependent variable of the variable value of frequency (f, measured in hertz).

I finally “got” calculus in college. Seeing it in the context of electronics made it crystal clear to me. Funny thing was some of the ones who 
were math wizards in high school couldn’t grasp the fundamentals of electronics. I survived in spite of it all :-)
