| Added an SUT...not sure I understood this getting back to the OP.... He seems to state that he expects 6-8dB of gain in place of the nearly 20dB that a 1:10 suggests. He then says he is getting the opposite effect which I take as less gain. for the OP. In sticking with just the 40Ω (... | |
| Why do tonearm specifications list null points? You need a mirrored surface with lines finely etched and magnification. and certainty that the diamond tracing faces (assuming advanced profile) are aligned precisely 90° to the cantilever. dave | |
| Cartridge Loading.....Part II I suspect that the mention of Lenz's Law with respect to back EMF may be a bit misplaced here. The simple story of back EMF when it comes to a speaker is the inertia forces the cone to continue to move after the signal tells it to 'stop and go th... | |
| Fact or misinformation? There is vertical compliance to keep the tip in the groove and handle record warps. Just higher compliance laterally. No vertical compliance means the stylus bounces in the groove from record warps. yes... and interestingly enough the choice of... | |
| Fact or misinformation? Lew, I agree that a mono switch helps. The big thing it does is converts all the noise to a mono signal since having mono music and stereo noise is very distracting. All of this based on the evil premise to some that you are listening to mono i... | |
| 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... |
