| Autoformers, The Benefits in matching amp to speaker A friend of mine had powered Acoustats; he got frustrated with them and handed the amps off to me wherein I renovated it and installed a tube input stage. It worked pretty well- the original opamp circuit just didn't seem up to the task. Very nice... | |
| MAC Autoformers? I know of no tube amp designer who uses SPICE. can you name a few?Nope. Maybe one? I know I don't! Victor Khomenko was trying to model our MA-1 in Spice many years ago before he became part of BAT. He called me up saying that the amp didn't run i... | |
| I need your help. I have an ARC Ref 3, ARC 110, Vandersteen 5As, but no turntable. Regarding the phono section:A good phono section will reduce the number of ticks and pops you hear without curtailing bandwidth.An excellent turntable to consider is the Technics SL1200G. IMO its weakness is its arm, but its arm is competitive wit... | |
| Tri-Planar Vll "SE Upgrade" I have the feeling that when raul is talking about 'lies' he is talking about me; just for the record nothing I've posted on this or other threads about tone arm or LP performance is untrue. Generally, if I don't know the answer I stay silent. If ... | |
| Autoformers, The Benefits in matching amp to speaker "An Autoformer or any transformer cannot fix a difficult load and only affects stability in a poorly designed, on the edge amplifier." @georgehifi That quote is taken out of context but despite that it still appears to be that you have missed the... | |
| MAC Autoformers? If Ralph (Atmasphere) picks this post up, ... what is the tube life is in your amps. Btw Ralph, …. Roger mentioned a couple of times that negative feedback, *if used properly*, is not all that bad a design feature. Not taking a position, just... | |
| Autoformers, The Benefits in matching amp to speaker So why did you stop making the Autoformers?Paul Speltz came out with the ZEROs. I think our device was better in some ways- it was EI core rather than toroid, and it had 1 ohm taps! But the ZERO proved easier to explain and since that wasn't our m... | |
| MAC Autoformers? He also had a set of our M-60s- really nice guy. | |

| Low power tube amp for Sonus Faber? According to a lengthy email exchange I had with Roger Sanders --over 40 yrs of ESL experience -- the jist of what he explained to me is that speakers with a 4 ohm rating will not actually perform at their state SPL range. a 91 db rated spea... | |
| MAC Autoformers? I did read your white paper before entering this discussion. Lets just agree to disagree. Peter Walker designed the 57 to be used with an amplifier with a damping of 20 and even specified the series inductance. To say that these speakers will p... | |
| Autoformers, The Benefits in matching amp to speaker I consider it a device that makes the problem go away.When we introduced our Z-Music autoformer back about 1990, we always regarded it as a problem solver. The same is true of the ZEROs, which is a similar product.Since we make OTLs, the problem t... | |
| Low power tube amp for Sonus Faber? The Sonus Fabers are such a rich, warm speaker I’m not sure that they benefit from the overtones of a tube amp, at least mine, in my room did not. So is this why the company that owns Sonus Faber also owns Audio Research and MacIntosh?It seems the... | |
| MAC Autoformers? @ramtubesRoger, you might want to read this:http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.phpIf the Quads were close to the wall behind them, they will often have one-note bass. This often happens when a solid state amp is emp... | |
| Low power tube amp for Sonus Faber? If I crank up the volume, am I risking amp to clip and damage my elipsa? No.i really wanna get the amp, I’m in love with it. Imagine putting monster truck tires on a British sports car from the 1950s- if you really want to experience the charm of... |
