Phon stylus inspection
I dont actually see any wear at this stage. i have only seen damage on others when they abused like DJ units-its a wonder some stay in the groove, mine are shibota like and never seem to change, i once put a laser on the tone arm trying to see the...

Amen to this Tube Amp post-we need more engineers on here...QUOTE  :;"’6-18-2018 2:05amThis is an old topic...literally. In the times when tubes were dominant amplification devises, the output transformer was a necessity (one might say a necessary...

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 ir...

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 induct...

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 filimentsource.   LOL.   AC is just a more convient source of power in the home now. Ok OK the motors may need 6...

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...

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 kno... 
Power regenerators X Power Conditioners
thats a mixed question as the THD is usually a result of interaction with a particular load-so it cant really be told unless you specify your phase leads/lags etc...The IGBT units are the best at fitting the general specs. like 3rd order harmoinic...

ive got some that are 128lbs, the batts are the weight.some units are 40lbs rack-with batts external on floor.there are many desktop units 1 kw 25lbs or less

excellent explination on the higher order harmonics.... Musicians know this stuff in and out and can appreciate harmonics big time since you tune string instruments for intonations,harmonics etc.... the music we hear or think about is usually more...

you seen my comment, buy a used commercial UPS for 800 and have better power quality than any "regen" unit cause thats what they are without the battery.https://www.ebay.com/itm/APC-Smart-UPS-XL-3000VA-RM-5U-SUA3000XL-New-Batteries-1Yr-Wrnty-FreeS... 
Is there actually a difference?
I had a friend who is now passed that ran a recording studio professionally and did hall n oats, todd rundgren and many private works out of Manhatten and NJ area. we used to play on stuff with the studio master tapes as source with totally uncomp...

Is there actually a difference?
The Amps are well known as 10k since 10000 watt is standard output each. The quality of sound is input=output uncolored or unaltered except for lots more. and i do have current sense Cts transformers at the loads 30ft away-feedback.and tube sound ... 
Is there actually a difference?
the constant current mode makes the only diff. eliminates all the spk/wire losses. a lowest pipe organ note still clean at 125 db. they dont run MRIswith all your Eseroteric Expensive names. The Techron M600s too for upper bass and highs. Never ne...
