| Fact or misinformation? But either way its a compliant diamond sliding through wiggles. A stereo needle will simply pick up the exact same movement on both channels. I do not see how this will damage anything. It comes down to whether the playback cartridge has verti... | |
| Fact or misinformation? The big difference between a mono cartridge and a stereo cartridge comes down to noise pickup. A true mono cartridge has the coils oriented to only pickup info in the lateral direction whereas a stereo cartridge is oriented with the coils at 45° ... | |
| Fact or misinformation? No. The situation where damage can occur is playing a stereo record with a mono cartridge that has "normal" lateral compliance and little or no vertical compliance. dave | |
| Cartridge Loading.....Part II Mijo, I agree that there is a big difference between loading @ 47kΩ and loading approaching zero. These two extremes very closely represent the "ideals" of current vs. voltage amplification. It may very well be conjecture but discussion of this... | |
| Cartridge Loading.....Part II Cutting and pasting text without any reference to context is not proof. Where was it ever proposed that heavy loading causes additional mistracking? It has been my contention that exactly the opposite may be occurring. Everything you mention spe... | |
| Cartridge Loading.....Part II All cartridges no matter what has a mistracking issues always and in every LP recording. If we accept this to be the case (and I do) then the next logical step is to agree that we are simply discussing varying degrees of mistracking. Treating ... | |
| Cartridge Loading.....Part II Who came up with the thought that cartridge loading affected tracking? That is rather silly. A guy named Lenz observed and documented the underlying concept and I'd hesitate to call his work silly. Now extrapolating his work to cartridge loadi... | |
| Cartridge Loading.....Part II If not loaded the transformer can 'ring' with excess harmonics- its making distortion. Your ears will respond to that as sensing it as loudness and yes, it might even hurt if the volume is up a bit. That is not the case in this instance. The m... | |
| Cartridge Loading.....Part II Whereas, Dave said that any device with an input impedance much lower than that of the cartridge internal resistance can act as a current driven stage. Is that correct? I am not suggesting that if the load is a fraction of the cartridge impedan... | |
| Cartridge Loading.....Part II @dover This needs to be distilled to the most basic level to get a solid foundation that everyone can build upon equally. It is not about any particular design and more about cartridge loading as a whole. My belief is that the nature of current... | |
| Cartridge Loading.....Part II OK... lets try a different tact since i do not think ground (be it virtual or real) matters in this situation. I am simply relying on Ohm and Kirchoff for this ideal case. Take a 30Ω cartridge and hook it up to an ideal voltage amp and then anot... | |
| Cartridge Loading.....Part II The question cannot be answered at all if current amplification is used. Why not? Consider the case to be an ideal current amp with the appropriate series resistance added so the input impedance is 5Ω. In this gedanken world the ideal voltag... | |
| Cartridge Loading.....Part II The topic of this thread is cartridge loading and it only makes sense to look at it from the two terminal perspective of the cartridge without concern of the "technology" used to provide that load. There are two basic extremes of operation of a ... | |
| Cartridge Loading.....Part II Ralph, The two statements you quoted from me seem to align well with each other and I was unaware that there was a different versions of ohms law for static vs dynamic loads At any rate, Moncreif threw off his numbers by using a 5 Ohm load I ... | |
| Cartridge Loading.....Part II I didn’t mention a dead short and was only referring to the two terminal impedance the coil of a cartridge sees. Any reference to ground be it real or virtual does not factor into the load seen by the coils. Surely there has to be an actual input ... |
