Linn Linto Brilliant power supply interchangeable with Linn Karik Brilliant power supply ?
It's all about matching voltage and current, and I doubt that a phono stage and a CD transport would have identical requirements, but it's possible.  Also, why not ask Linn?  In fact, definitely ask Linn before taking any advice here.  
VTL MB-450 or Manley studio 440 input voltage modification
Bill, that's a viable idea, but these behemoths pull a lot of current, and one would always wonder whether the step down was doing a good job of supplying same.  So maybe if you used a step down with a 2X or higher excess of peak current draw it w... 
SUT - electrical theory and practical experience
Raul, to state the bandwidth of any transformer, particularly an audio SUT, without specifying the upper and lower limits of the given bandwidth in db, the impedances on the primary and secondary windings, and the other reactive components of the ... 
System that sounds so real it is easy to mistaken it is not live
I think Mr Volti was a furniture maker before he went into the loudspeaker business.  His cabinet work is certainly first rate.  
System that sounds so real it is easy to mistaken it is not live
dogberry, No one, least of all me, is dismissing full range ESLs. That’s exactly what I listen to in one of my two systems, Sound Lab 845PXs, with no subwoofer. One reason for no subwoofer is my disinclination to clutter up the listening room any ... 
System that sounds so real it is easy to mistaken it is not live
Mijostyn, I appreciate your unequivocal convictions on nearly all things audio, but don’t you think you’re a bit over the top or around the bend in subwoofers? The ONLY worthwhile design is the dipole??? Really? I do like the idea of the dipole th... 
SUT - electrical theory and practical experience
Drbond, transformer theory is a deep subject. The only person with deep knowledge who ever posts on Audiogon is Dave Slagle (Intact Audio). Otherwise you are not going to find enlightened discussion here. I suggest you do an internet search. The s... 
Simplest Linear PSU?
Regulation done right typically reduces noise. Done wrong or badly or with defective parts, I suppose it could add noise. Even for a home built LPS, there are excellent prefabricated regulators available as add on devices. Most important is to pla... 
System that sounds so real it is easy to mistaken it is not live
We once calculated that my speakers have about 400 in.² greater radiating area then do yours. Perhaps that’s where our results differ, because my speakers are not perceptibly distorting in anyway at 100 Hz. And there is the added value of coherenc... 
SUT - electrical theory and practical experience
My Johnson is very quiet without a SUT, speaking for myself only. But seriously folks, Ralph (Atma-sphere), you have often mentioned the notion that high gain phono input stages need to be designed to be insensitive to RFI.  What design elements ... 
Simplest Linear PSU?
Regulation done right reduces noise on the supply, rather than adding noise.  
Stylus skipping at beginning of record
Even zero AS ought not to cause your problem although I’ve never used your particular tonearm. One has to wonder why your “technician” left you with zero AS, however. Usually zero AS causes noticeable distortion especially in the R channel. I adju... 
Simplest Linear PSU?
Building a good LPS is or can be a little more complex than implied. It helps to have an oscilloscope to analyze the performance, too. Learn about pi filters, etc.Also, you may want to regulate the V output in which case you design for a higher V ... 
System that sounds so real it is easy to mistaken it is not live
SL used to make and sell a single huge ESL woofer panel to be placed in between a pair of their largest speakers, then called the A1. They also made add on wings for the A1, to attenuate the back wave and reduce cancellation. That becomes less nec... 
SUT - electrical theory and practical experience
"Are there any inherent weaknesses in a SUT versus a transistor, or vice versa?" If I didn't know you were serious, I would suspect you of being a troll based on this sentence.  The question has already been broached here in this thread.  Elsewhe...
