| Fuse Direction for Pass Labs Amp and Preamp Inescapable FACT: No one understands exactly how electricity works. That’s why there’s so much Electrical THEORY. People risk their lives on electrical theory, just as they do the theory of flight. I suspect you might mean 'hypot... | |
| Cartridge Loading for a phono pre amp While mechanical impact does occur as a result of electrical load- there is some back emf necessarily generated by the signal current that affects the mechanical motion, but a quick back of the envelope calculation using Lenz’s law and the 10uH c... | |
| Fuse Direction for Pass Labs Amp and Preamp None the less saying something is hogwash, is hogwash especially when it comes to cables and wire direction. It’s simple, cables sound and work differently in one direction than the other. The reason to condition cabling the direction it is pushe... | |
| Fuse Direction for Pass Labs Amp and Preamp You never owned Bose 901s or have read why Amar Bose designed them that way, I'm guessing. @russ69 This is such a great example of what I'm talking about (the myth bit)! I'll put it to you this way: If someone comes up with a way to get home s... | |
| Fuse Direction for Pass Labs Amp and Preamp I am thinking that the direction should be the lettering left to right with the beginning of the lettering facing out of the amp and the end of the lettering facing into the amp. Does this sound right? @mitchb Not unless the fuses are in a DC... | |
| Cartridge Loading for a phono pre amp How does this concept affect the transimpedance phono amps? The input impedance is also known as 'virtual ground'. This is a point in any opamp circuit where the feedback is applied back to the input of the opamp. There is a resistor that also ... | |
| Cartridge Loading.....Part II Recommended loading is between 91ohms and 47kOhms determined by listening. @quincy I love that Lyra states things this way- Jonathon Carr is well aware of how differently phono sections behave when presented with the RFI generated by LOMC cartr... | |
| Thermal Distortion your loudspeaker most likely suffers from it. But do you care? If high efficiency speakers are so darned good, why did the industry move away from them? So electronics makers could sell more expensive Power? Methinks not. @ieales The industry moved away from higher efficiency because its expensive, when ... | |
| Cartridge Loading for a phono pre amp Raul is obfuscating. His contention is that loading has no effect on the compliance of the cartridge. I showed that it does. Since the amount of energy directly affects how much force it takes to move any generator by the direct proportion of e... | |
| Cartridge Loading for a phono pre amp So you're not going to answer my question? That leads me to think you are simply trolling. Because there are internal losses, the cantilever will not be quite 470 times harder to move; we'll call it 400, assuming that its also designed to operate ... | |
| Cartridge Loading for a phono pre amp @rauliruegas I see you are refusing to answer my prior question to you. I've handed all the information you need to you on a silver platter. But the way you are reacting suggests you are not here for any other reason than to troll. If that is not ... | |
| Cartridge Loading.....Part II I don't know what implications there would be with a SUT. I suppose this is all variable, depending on the capabilities of the phono stage, as Ralph @atmasphere seemingly explained in the previous thread. Normally you have a rather prodigi... | |
| Cartridge Loading for a phono pre amp The cartridge. @holmz Oh man, you're doing Raul's homework for him😄! I suspect you know how any generator will respond when asked to do say, 470 times more work? BTW you are correct that the output voltage isn't the same with the two different ... | |
| 45 Type Push/Pull there is something about pp that is overlooked: the output and interstage transformers fall in and out of magnetisation at every zero-crossing of the signal (at every polarity change). This is only correct if the amplifier is biased class B. ... | |
| Cartridge Loading for a phono pre amp 50K ohms, all inputs. (Magnetic phono may have any value from 10 ohms to 100K ohms substituted. Also has provision to add input capacitance for matching certain magnetic cartridges.) The preamp has a 49.9K resistor to ground, but has other elem... |
