| Do speaker cables need a burn in period? no difference for breakin or direction.variable AC exhibits skin effect and parrallel capactive coupling in all speaker wires proportional to frequency carried. 0-20khz is no problem.only when you go a few 100khz do standing and reflected waves im... | |
| AC Regenerator 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 run... | |

| AC Regenerator 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.https://www.tripplite.com/isolator-series-120v-1800w-ul60601-1-medical-grade-isolation-transformer-6...https://ww... | |
| Phon stylus inspection the best alignment is run a test stanard record which is exact as can be both right and left modulation in the groove. hook up a 2 ch oscilloscope to each side and look for any differential side to side and adjust for minimum ouput scope on additi... | |
| 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... | |
| MAC Autoformers? 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... | |
| AC Regenerator 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... | |
| AC Regenerator 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... | |
| AC Regenerator 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... | |
| AC Regenerator 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... | |
| AC Regenerator 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... | |
| Power regenerators X Power Conditioners 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 | |
| MAC Autoformers? 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... |
