Ultrasonic Oscillation
HEY, Tim- R U still out there, somewhere(timru)? 
Interesting look at THD
If you're concerned with noise on your neutral or ground and actually want to test for it, some years back there was a discussion regarding AC line noise and conditioners(https://forum.audiogon.com/discussions/analyzing-the-power-from-the-outlet),... 
Do caps deteriorate with time even if an amp is not being used?
A big YES! Though(often) careful reforming can restore them(their dielectric) to original specs. (http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.823.6133&rep=rep1&type=pdf) If you’re going to buy that amp, buy a variac too(unless... 
PS Audio Power Plant Premier THD Output Results
The Power Plants will display both incoming and outgoing AC distortion on the front panel. Otherwise, a separate AC Quality Meter is required. There are a number of examples here: (http://www.ebay.com/sch/i.html?_odkw=thd+meter&_osacat=0&_... 
Interesting look at THD
Read it twice earlier.   Didn't see anything applicable to audio, regarding the industrial, "remedies" mentioned.   I must have missed something. 
Interesting look at THD
You do understand that the article concerns Variable Frequency Drives and Power Factor Correction problems, in an industrial/Three Phase environment, rather than audio, right? Just my opinion, having worked in that, as well as home and pro audio, ... 
Interesting look at THD
Yes, it and they are very interesting to look at! 
Agoners: Need Advice! Have 3K to spend on an Amp, what do I do with no way to audition?
You mentioned, "no audition" as a concern.  Both Odyssey and Sanders(Magtech) offer thirty day, no questions returns.  Klaus' amps are made right here in the Indiana and fit well within your budget. 
What to add or change for my system?
Do you have dedicated AC breakers and lines, going to your system/listening room’s outlets? I wasn’t so much surprised, as I was delighted, when I installed a couple runs of 10 AWG Romex(twisted together) to mine. And YES: room treatments/cabling! 
Anyone have a pic to show me where to replace HEXFREDS in a Cary CAD-120S?
"Two caps only."(per)   I'd want to keep the capacitance within 20%(and I always prefer the more side).   I've already put over $800 worth of Duelund coupling caps in the pair, not to mention a few other little expenditures.   This will take some ... 
Anyone have a pic to show me where to replace HEXFREDS in a Cary CAD-120S?
You answered while I was editing my post. Figured the TCs were the ones referenced. I was wondering how you accommodated them(nice work). 
Anyone have a pic to show me where to replace HEXFREDS in a Cary CAD-120S?
grannyring- Where’s a good place to find 1200uF/450VAC(or thereabouts) film capacitors? Seems they would have to be huge and very expensive.  ie: Eight Clarity TCs in 600uF/450V caps would take up over 67 square inches of landscape.  I do love the... 
What's your favorite album cover art ?
Blind Faith/1969(I was much younger then)!

Follow your hot and neutral power cord leads(within the chassis) and among first connections, you’ll find three diodes, connected in series to each AC lead. Three will be facing cathode to AC supply lead and three: anode to AC lead. Mine had a sin...
