| 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... | |
| "Breathing" of the air 'Air' is one of those things that, IMO, all audiophiles think that they are talking the same meaning, when I think you will find that there are several predominate meanings.For me, 'air' is the ability of speed in a system, in a way that allows fo... | |
| Grado 10K Ohm Loading? In the past (before the wood body Grados appeared) we ran the loading on the Grados at anywhere from 7K to 10K with excellent results. I can't speak for the current lineup, but on the lower priced models I would not be surprised in the least to fi... | |
| how valid is a nagra recorder Absolutely. The Nagra stereo machines are excellent. | |
| Repairing older amps If you are looking at older amplifier, whether tube or solid state, after about 15 years or so you will want to consider replacing the filter capacitors in order to maintain the reliability and performance of the amplifier. Often filter caps will ... | |
| Speakers and Tube Amps Cleaneduphippy, you can also have the case where the impedance goes high and the tube amp will put out constant power. This is OK if the designer expects that. Impedance dips are usually not a problem too, as you have to sometimes shut down the ou... | |
| Help all ye Triplanar Gurus Sunnyboy1956, I've known Tri a very long time and this story did not sound right, so I gave him a call. Turns out their emai l has been down the last month or so and they are in the middle of changing ISPs (and apparently, doing a whole lot of con... | |
| Ortofon Per Windfeld Load Impedance? Zieman, the traditional problem with long interconnects is loss of high frequencies. I say traditional because the case of a low output moving coil is a special case. The source impedance of the cartridge is very low- often only a few ohms. Althou... |
