. .. The scary thing is that Studer used the 301s in a bunch of consoles and actually managed to make them sound good. I'd never have believed it if I hadn't heard it for myself. All things considered that drives another nail in the coffin of the theory that slew rate always matters. Not at all; it simply means that you need to take due care. Compensate the 301 for the actual gain being used (if it's unity gain it requires less compensation, which means higher slew rate) and keep the levels low in devices operating at low slew rates. If the peak level doesn't exceed 0.5Vpk, and you are conservative about loads, even a 741 will perform fairly adequately. It won't win prizes, but it'll be all right. Try to get more voltatge out, however, and you run into slew problems quickly. My guess, without seeing the schematics, is that Studer kept operating levels down in their board, compensated 301s for whatever actual gain they had, and used feedforward for summing amps and, with current-boosting transistors, outputs. (Feedforward got you something like 10V/us in a 301, but could only be used in inverting mode.) Ed Gately did something similar with his mixers in the 1970s. Peace, Paul |

... And how do you remove the transformer and still drive a 1200 ohm load? The schoolkids want to know. BTW, the 301 is a single package opamp. Nice of National to provide the LME49710 ! The 460B uses a TI TL062 dual fet input device. Good luck getting a single package device to work in there. A TL062 ? That's as noisy as hell ! That may not matter, depending on the level it's being presented with. The thing that makes substitutions tricky in this application is that the new opamp has to draw no more current than the original; you're stuck with the limitations of a phantom power supply. I don't know what opamp Jim Williams substitutes for the 301 in that modification, but I bet the choice was non-trivial.. Peace, Paul |

All things considered that drives another nail in the coffin of the theory that slew rate always matters. Part of the secret is to never put more than 20dB of gain on any one stage, it seems. This part has only 1 MHz GBW. That means that a stage with 40 dB gain may start rolling off with -3B @ 10 KHz. Well ... the very popular and 'designed for audio' TL07X series only has 3 MHz GBP ! The difference between -3dB @ 10 KHz and -3 dB at 30 KHz is very audible. 10MHz seems to be more the norm for more modern audio parts. That pushes the 40 dB gain -3 dB point up to 100 KHz, which is gives adequate margins. It's even arguable whether a -3 dB point above 100 KHz is a bug or a feature! |

Yeah, but you don't want that -3dB point to happen because you've run out of loop gain. It's a good way to get crappy results at high frequencies because of insufficient feedback. Quite a few years ago I read an interview with the boss at Benchmark. He was asked how they get away with using the much-maligned 5532 dual opamp for most of their designs; he replied, in essence, that if you rolled the high-frequency response off well before the closed-loop curve ran into the open-loop, and watched out for loading, the 5532 could give very nice results. Their products seem to confirm it. Peace, Paul |

On checking, you are right. I falsely remembered it as an LM301 from last time I looked. Surely there is a drop-in replacement ( or more recent manufactured 062) for that, that would give a marginally better performance ? TLC 272 very likely (just off the top of my head without even bothering to look). Who said anything about removing the transformer (OK, you might in your upgrade) . A few replaced electrolytics (esp tantalums) may also give an improvement.And then one could put bypass caps on those, espcially the series with output before the transformer... I know schoolkids who do that sort of thing off their own bats. Admittedly through folkloric methodology rather than scientific. The xfrmr in the stock C460 is rather disgusting, and Jim removes it. The best thing to do with most audio transformers IMHO. Unless you're using them as an 'effect' per those early Class A Neve modules for example. Graham |

Yet our world was deeply changed by the difference between the approximations and the real world. Much thanks, as always, Chris Hornbeck |

Science is the process of attempting refutation. And engineering is flying blind somewhere in between. So's life. In short, 'belief' requires that one must dismiss facts as inconsequential and give preference instead to story telling. Hence religion must be seen as a cancer on the world. And I would say that "belief" is a practical compromise in a given situation in order to take the next step without falling. Do you really, really believe that there's a solid ground there in front of your foot? It's a leap of faith, and in some attic, someday, might prove to be unwarranted. We never, ever, ever, know the "truth" or even anything vaguely remotely like it. We only ever see or hear a magnificently orchestrated simulation of it, all constructed by three pounds of wetware. Folks in our biz know something of the current impossibilty of understanding our listening process, but would be astonished at the processing involved in vision, which we "believe" completely. All of the rectilinear geometry and color variations, to give two high-profile examples, are *completely* internal constructs - totally simulations. All generated by computing horsepower. But we "believe" our vision completely. We can't even choose not to. (Story telling and myths are a separate subject inappropriate to the newsgroup, but are IMO separately valuable elements of humanity). Much thanks, as always, Chris Hornbeck |

The idea that it's some difficult task to find a better device then an LM301 simply shows that the person suggesting such an idea is DECADES out of date with modern practice. Not necessarily. An IC going into a microphone running from phantom has to be low-current *and* low-noise *and* low-distortion, and (if it's driving the output and the output is transformerless) has to be able to operate cleanly into a 600-ohm load. Depending on the surrounding circuitry, input bias current may be an issue, or not. Getting two or three of those right is, as Eeyore suggests, not that hard with some perusing of catalogs and bench testing. Getting all of them right, well, that might be a little tricky. It's the requirement for low current that buggers up the situation. Peace, Paul |

... But I'll give you an alternative viewpoint: Science *is* complicated. Science has the questions. Sometimes, if we're lucky. Science ALWAYS has the answers. It would be a disaster if it didn't. Excuse me, but just about any scientist would disagree. S/he would say that science has SOME of the answers, SOME of the time, and is always looking for more. It's also always looking at the answers it has to see if they might be wrong. Just to get even farther afield, science has answers to some questions, but is not the appropriate tool to answer others. A classic example: It is proposed to build a new factory in an urban area. It will generate lots of economic activity, which makes the standard of living better, so most people will live longer and more comfortable lives. However, every year about 500 of the residents, mostly children, will die from cancer because of emissions from the factory. The question, which science cannot answer, is this: Is it worth sacrificing the lives of those children (and the suffering of their families) to improve the general condition of the community? Science can provide a lot of information: it can tell you what pollutants are emitted from the plant, and what their physiological effect is, and it can predict the number of deaths (given enough data about similar installations in the past). It can also make a stab at predicting how much economic good will result from the factory, and how much the standard of living will rise because of it, and what effect the rise in standard of living will have. In short, it can provide the pliuses and minuses of building the factory. It can tell you what the effects will be, good and bad. But it can't tell you whether to build the factory, because the decision -- once you know the facts -- is a *moral* decision, one based on your values system. Is business activity more important than the lives of individuals? Or not? (And it's of course complicated by the fact that business activity which improves the standard of living also saves lives.) Going way, way afield from cables and Jim Williams's microphones, but it's an example of some questions science can answer, and one which it can't. Another question which science can't answer -- yet: What is the nature of dark matter? I suspect, if we don't destroy ourselves, that science *will* answer that one in a few decades or maybe centuries. Right now it can't. (Of course, the answer may be that dark matter doesn't really exist. But that's looking less likely, from what I hear.) Oh, one other thing: Eeyore says that science always has the answers, and would be a disaster if it didn't. Sometimes, it thinks it has the answers, and is wrong. See "thalidomide". Peace, Paul |

Audiophool 'BELIEF' (a.k.a religion) counts for nothing in the real world.. But I'll give you an alternative viewpoint: Science *is* complicated. Science has the questions. Sometimes, if we're lucky. Pklease give modern science the credit it is due. Science has an incredibly larage lot of very good relevant answers. Strictly speaking, all of the answers that science has are provisional. There may be a better answer, a new generation answer, around the corner. Sometimes science's previous generation of answers are so good that we still use them, even though we know better. One example is Newton's laws of motion, as compared to the more recent, more complex Einsteinian laws of motion. Newton's laws are still used almost all of the time, because they are sufficiently accurate for almost all purposes. Newtonian laws of motion are sufficient to explain how the mechanical parts of a microphone work in everyday use. Ordinary electrical engineering is sufficient to explain how the electrical parts work. Modern psychoacoustics science is sufficient to explain how it all interacts with the ear. Tom say that we have the answers is the end of science and the beginning of religion. With due respect, that's a straw man argument, because we don't need to invent any new science, or claim that the old science has all the answers, to figure out the sonic implications of capacitor upgrades to microphones. |

Furthermore, many parts of many religions are actually very pragmatic. In short, 'belief' requires that one must dismiss facts as inconsequential Again, not necessarily. Strictly speaking, belief in science is well, a belief. and give preference instead to story telling. Science is not really any any different on that point. A scientific paper, at least a good one, just tells a story: I had an idea. I decided that if my idea were correct, this special thing would happen. I tried to make my special thing happen. I suceeded in making my special thing happen. Therefore, you should believe my idea. This is just another special case of Kurt Vonnegut's outline of all stories: There was a man. The man fell into a hole. The man got out of the hole. Hence religion must be seen as a cancer on the world. Many instances of religion seem to work out that way. But so do certain ideas about economics and politics and other things. You're going to tell me that Marxism wasn't a cancer on the world? ;-) |

That's where science differs from superstition and religion. The miracle needs to work every time. Somehow, there's always a reason why it doesn't. |

Just to get even farther afield, science has answers to some questions, but is not the appropriate tool to answer others. A classic example: It is proposed to build a new factory in an urban area. It will generate lots of economic activity, which makes the standard of living better, so most people will live longer and more comfortable lives. However, every year about 500 of the residents, mostly children, will die from cancer because of emissions from the factory. The question, which science cannot answer, is this: Is it worth sacrificing the lives of those children (and the suffering of their families) to improve the general condition of the community? That science can't answer a simple question like this is highly questionable. Science can provide a lot of information: it can tell you what pollutants are emitted from the plant, and what their physiological effect is, and it can predict the number of deaths (given enough data about similar installations in the past). It can also make a stab at predicting how much economic good will result from the factory, and how much the standard of living will rise because of it, and what effect the rise in standard of living will have. Science can also tell you the economic value of the lives of the 500 children that it is proposed that we sacrifice. In short, it can provide the pliuses and minuses of building the factory. It can tell you what the effects will be, good and bad. But it can't tell you whether to build the factory, because the decision -- once you know the facts -- is a *moral* decision, one based on your values system. I don't think there are many thoughtful intelligent people who seriously think that Science is that totally disconnected from morality, and vice-versa. The idea that science and morality are disconnected would be something that maybe a Hitler or Stalin would propose. Is business activity more important than the lives of individuals? Or not? (And it's of course complicated by the fact that business activity which improves the standard of living also saves lives.) This factory problem is one that has been worked out many times. In almost every modern case, the lives of the 500 children have the greater value. Going way, way afield from cables and Jim Williams's microphones, but it's an example of some questions science can answer, and one which it can't. There are many questions that science hasn't answered, but we don't know what questions it can never answer. Another question which science can't answer -- yet: What is the nature of dark matter? I suspect, if we don't destroy ourselves, that science *will* answer that one in a few decades or maybe centuries. Right now it can't. (Of course, the answer may be that dark matter doesn't really exist. But that's looking less likely, from what I hear.) See, you made your question reasonable by including a weasel word: yet. ;-) Oh, one other thing: Eeyore says that science always has the answers, and would be a disaster if it didn't. Well, if you look at the big picture of science, I imagine that you can logically say that science does have all the answers, we just haven't wrestled some of them away from her. ;-) Sometimes, it thinks it has the answers, and is wrong. See "thalidomide". Bad example that is way too easy to deconstruct. But this post is getting long and I'm getting hungry for breakfast. Later. ;-) |

Simple economics, just include the cost of cleaning up in the manufacturing budget, otherwise a known cost is omitted and that seems to me like malpractice. Kind regards Peter Larsen |
