| otl vs push/pull FWIW Israel did a lot of the formative work on his speaker line with a set of M-60s. We have a set of his Total Victories which the M-60s drive with ease.But to the point of OTL vs P-P, for the most part, OTLs **are** push-pull. The elimination of... | |
| Help choosing coupling caps I stand corrected! I have to assume that the paper and oil parts that I saw in their catalog a while back are no longer made.I assumed from the size of the parts (they are used in the crossover of my speakers) that paper and oil was the technology... | |
| How does OTL amp get its power? You could also wait until I find this thread :)I'm not sure what you mean by 'OTL amp get its power'... of course the power comes from the wall :) seriously though an OTL amplifier is able to make its power in a way that is not unlike a transistor... | |
| Ortofon Per Windfeld Load Impedance? Jloveys, that might be true on a track. But trucks are intended for use on the road, something that Formula cars suck at- their engines are not tractable since they are intended for power at high rpm. Additionally, many trucks will handle and ride... | |
| Help choosing coupling caps Musicfile, FWIW, there is no such thing as 'too much detail'. Also FWIW a lot of people associate brightness with detail, the two have nothing to do with each other.IOW you can have an extremely detailed system that is at the same time very relaxe... | |
| Thoughts on cartridge loading with a SUT. Here is more information regarding Dave's spot-on info on the Jensen transformer website.http://www.jensen-transformers.com/mc.html | |
| Ortofon Per Windfeld Load Impedance? Jloveys, when you can measure a thing in audio, and also hear the same thing, then you have a powerful correlation that cannot be denied. Critical damping of any inductive device, whether it is a coupling/setup transformer, phono cartridge or tape... | |
| Triode or Ultralinear Learsfool, you might also include push-pull triode amps in your quest; not all that is triode is SET. | |
| Help choosing coupling caps Musicfile, IME **all** paper and oil capacitors can exhibit an electrical leakage over time that can wreak havoc in your amplifier if used in the output section. This is because the electrical leakage will mess with the bias voltage on the grids o... | |
| "Breathing" of the air Mrtennis, its true that you don't hear air, its simply the medium. But- the audiophile term 'air' means something different from what you are getting at in your comment. When audiophiles use this term, it implies a quality that the system is doing... | |
| Ortofon Per Windfeld Load Impedance? Larry, ya know, that's something I've often wondered myself- not only how manufacturers arrive at their loading specs but also why more of them don't do anything at all. This is a technique that does not require a test LP, or even a turntable, and... | |
| Triode or Ultralinear Well, Tvad is right as long as this is occurring inside one amp- like if you have a switch to go back and forth. But- if you compare real triodes to pentodes **wired** as triodes, you will hear a substantial difference.Ultralinear is a way to appr... | |
| Ortofon Per Windfeld Load Impedance? Larryi, if you just use your ears for loading a cartridge, you will indeed arrive at different values for different phono sections. That is because different phono sections sound different, some are brighter than others due to the use of negative ... | |
| Needing an explanation of amplifier feedback Adampeter, while all that Al mentions is true, negative feedback has a negative consequence- it increases odd-ordered harmonics in the range that the human ear uses as loudness cues. This is actually more important than frequency response- if you ... | |
| Pin declaration of balanced input / output XLR Dev, I think you will find that the invert switch does not do what you want all the time- the reason for this is that about half of all recordings made are out of phase. There is absolutely no reason for concern about the equipment with the switch... |
