RE: Normal-mode versus common-mode.

Hi Stu!

"most cables employ a twist like a left handed thread. In fabricating power cables from scratch, I find and a right handed thread twist imparts a much "faster" sounding cable, indicating that there is a hell of a lot of inductances going on."

Hmmm, actually most of my powercords are flat. (Perhaps that's why I get a smooth, flat response?) I've never paid any attention to how cords are twisted, I'll eyeball them next time I'm in the hardware store. Do you think it affects their mutual inductance?

Putting the crystal in the center would certainly get it in the high field region. Lot of interesting things to look into and contemplate in this hobby...

You know what Stu? While I used the toroid you sent me to good advantage, I still have the crystals and blu-tack in my drawer. And I just went downstairs and dug them out! I'll play with them and see what I can hear and/or measure. The weatherman says this is going to be an excellent week for inside projects so all is good.

Well... except maybe for the heatpump which quit pumping yesterday. But surely, in the name of safety, I shouldn't work on it in the rain!

Regards, Rick the rationalizer
