AC Regenerator

Hi I been reading all you guys responses.
Im a retired mad scientist from many govt and reaearsch areas of expertise and also an audiophile and musician.
Well im here to tell you all if you just buy a good big UPS battery supplied medical grade line voltage system your power will be a pure sinewave like you wont belive, its got to be a true sinewave not a cheap version unit. they dont cost as much as the stuff your talking about and we used them in Neclear reactors,MRIs and super critical analysis equipt all the time with excellent results.
yes the incomming line is garbage especially with all the new switching PS oscillators noising things up. So you cant get purer power than a properly modulated DC source. I run a few 8D 12 volt batts X10 =120 volts and a Techron Gradient amplifier(Crown) for 10000 watts of pure power where i can tweek the 60hz up and down at will and avoid inductor phase shift .
The E bag medical grade 5kwatt ubits are reasonable cost try it and see.
pardon the typing I got parkinsns.

oh I also remembered that tripplite made some super units that you can monitor and control with your PC and they go cheap from the computer server world often just needing new battery banks. Sola alo make some nice simple units. The Techron way is just my wierd method of  doing it,

Ive setup major rock band sound boards with them to stabilize their setup when going all over to different stadiums and countries-yet the feed the sound equipt sees is always the same as it was set up in the studio. again e bad all over the place. avoid the chopped wave cheap chinese ones. also you can set up each phase to run different equipt while being isolated from the house groung line which is usually noisey and offset especially round dry climate and grounding points. Ive seen ac offsets of 40 volts on the ground rod at service entrance where the soil was not conductive enough.
Dont trust home Grounds ever!!

Im currently working with one of NYs prominent Brain Neuralogists on stimilation of serotonin,dopamine,norepiephrimn with magnetic and RF and audio signals modulated upon music that the patient "likes" and it proves to work with 73% double bling exp.
im also using this to solve opoid addition by blocking the mu receptors like the drugs work. some major chemical details there that i wont getinto here. and lots of ion electrical excitation too. rememer every thing got a resonant freq(smile) got to love 432hsz.
anyway A regenerator is really a fanceyIsolation transformer with extra filters on in and outs nothing more. sorry vendor!!
read my link for audio physics for some good stuff.
Look at your signal on a good scope.
and nightime is when the line wave gets a bit cleaner cause most of the noise inducing motors and swithced supplies and not getting used.
do the math, the inducatance also of  old light bulbs tungsten -used to filter out some high freq line noise but with all the CFL and LED bulbs they are no longer in your house to be unintended RF filters/bypass loads.
I get into it on a regular basis with my local utility for the heck of it about all their "noise" even though i got it filtered-its just fun to be a pain in the butt for them and keep them honest

I have, but they were early ones in 90s. sorry for not updating my tear downs in 25 years. Im betting they are similar to the VFDs inverters starting with rectified filtered DC sourceed from isolated ac input. but prove me wrong and post the schematic if its not pripotary.
ill build one for cheap. some 2n3055s  are always good.
 I need a good physics discussion with a PHd in DC ion fields please PM me for an offline talk.
thanks
 

read link- see how much your wife drying her hair dupes your sound power supply and see how much JUST an isolation x former helps.

has anyone ran a comparison of the signal on a real digital scope vs what the unit is telling you?? The units that i had seen calculated THD and the sinewave for the readout with software but did not actually measure said aspects live online.I know this because i have scopes and THD analyzers on line at all times. ps Just bought another THD unit today. the frequency chop in the AC oscillator part has shown noisier than that output of a good UPS and a IGBT AC drive. too many high order harmonics. 
again I say run your stuff on DC battery power and compare.
just about every componet converts the AC plug into dc later anyway,
this is the next phase of top line audio equipt.
Hint-the military does this for many critical instruments and not for fear of loosing power. For finite noiseless signals and NO ground loops ever.

By using 50% or over will increase all harmonics and output stability,
see design specs used for all critical power systems. it can be shown in the math-do it and see, thats why Mil spec calls for 3 times rated load capacity. use that for your feed and enjoy improved power signal

Also please use Power Factor correction Caps on your Listening area power ,cause all the X formers cause a bad phase shift in input voltage otherwise. a few 100 mfd caps across 120v line for every 1000watts is good. or go to 3 phase as Vrms beats the .707 instantenuous value

my point is that there are tried and true standard ways of fixing up all your power problems and therefore your resultant sound without giving into the marketing hype of regerative sales at like 1/4 the cost.
IE- pro studio recording desgns.
Heck just going to balanced/isolated ground inputs can bring noise floor up 10 fold at little cost. to you.

Tubes work best on pure DC!! the electrons and such know their valance bands and holes to jump or get pushed into amplifying fronm the filiment
source.   LOL.   AC is just a more convient source of power in the home now. Ok OK the motors may need 60hz Synch but nowadays most all run DC PWM anyway. the physist in me had to let loose on you. sorry.

Holy cow!!! that things expensive.... You guys got too much free $$$$.
a pure sinewave UPS with an external THD and scope digital analyzer and protection from loss of power is like 1/2 that cost. the many utility transformers and line losses are irrelevent to your final load after the UPS also with better than 1 volt regulation. and you can run 5-7000 watts not only 2000. IM in the wrong business... LOL.
If a digital bigscreen is improving from a line feed correction something else is wrong with your system. sorry. maybe if things were still analog you would have a excuse.
I say do as you with its your money..
the intergrated scope and analyzer is calibrated to whos and what standards- NIST-MIl Std. with what traceability????

The howl it made trying to handle a plasma TV drove me crazy especially considering that the PS Audio tech staff said there was nothing wrong with it.  

switching power supplies dont like driving other swithcing PS cause the load changes inductance and capacitance so much depending on the varing Load. they like constant impeadances  like a load resistor across the output.. like driving difficult computer systems.
well known in the Server world look at the huge inductors on the main feedsw to smooth out the ride.

please see below buy these 2 and your power will be heavanly good plus safer than ANY regen. and lots more capacity for your Amps too.

Im not familiar with these newest models, I know the early ones did not offer anything i am asking about these $5000 units.
what is the claimed output distortion under continuous full load?
can they drive 5000 watts on a continuous basis without running hot?
what does it do during a momentary power glitch?
can you program all the operational parameters?
