| Phono rig capacitance Lewm, can you please give a link. I have looked on Jensen and not seen these specs. Thanks. | |
| Phono rig capacitance I tweaked the model, after reading another paper on tranmission lines etc.. I found a model that made sense and demonstrated the correct db gain and presented a familiar looking bode plot. I think this lumped model may be correct, or at least "bet... | |
| Phono rig capacitance Hi, According to this link the: "...Remember,the inductance is proportional to thesquare of the turns ratio. In the ex ample above, a turns ratio of 1:3 gives a 1:9 inductance ratio..."they they proceed to use 100uH : 900 uH. I have not even got t... | |
| Phono rig capacitance Typo: Under item "4) ...place the RCL for the wire connectors.." I do not mean wire connectors, I mean wires or interconnects. | |
| Phono rig capacitance Thanks Almarg, for you insight. as to the items: 1) In the K statement I have modeled it as a perfect SUT, this can be seen the by the 1 in the " K L2 L4 1". I can use numbers of less than one to make up for losses due to the SUT, like .6 .7 .9 et... | |
| Phono rig capacitance agreed John. Once the model is set. However once it is set is easy to simulate with software which is a more flexible and visual way of observing the data. The thing is, the basic model is not complete. Have you looked at the links above to see ho... | |
| Phono rig capacitance Link was not working lets try again: http://s27.postimg.org/aage8hg2r/Attempt_at_Circuit_Model.pnghttp://postimg.org/image/6e32chv33http://postimg.org/image/6e32chv33/fullHopefully one of those links works. | |
| Phono rig capacitance Hi guys, I have been having a lot of trouble modeling this correctly with the SUT in the mix. I am sure I am making some silly mistakes but I can't find them. Here is a link to the image of the simulation + circuit model. I tried to follow the mod... | |
| Benz micro glider vs dynavector 20X2 I tried the Low output version of the 20X2. It was in my system for about 3 days before going up for sale. I did not find this to be a neutral cartridge and did not appreciate the dynavector "house sound" at all, I also found that it had trouble r... | |
| Phono rig capacitance I can say I only partly understand, I will have to learn a little more to fully wrap my head around how it works. However, for now: I tried modeling the transformer, not sure why I am running into problems here. I will try to post the image later ... | |
| Phono rig capacitance Jcarr, Maybe I am off here but on the primary side/ what the cartridge sees: Do you not divide by turns ratio square i.e/ 10^2 or 100 in my example. So: 47K becomes 470 Ohms 100 pf SUT to Preamp becomes 1 Pf ??I would have thought that this implie... | |
| Phono rig capacitance Wait a Minute I had a dull moment let us redo this:Too bad there are no edits, now the mistakes look silly forever. Assumptions/Signal ChainCart[x uh,30Ohms , wire(100pf,2uh,1 Ohm)->SUT->(Same wire)->Preamp(47K) Cart sees everything on it... | |
| Phono rig capacitance Just realized your user is set to, Private and I cannot PM you. | |
| Phono rig capacitance Jcarr, Please email the white paper, you reference in the thread I am exceedingly interested in reading it!!!! Thanks. I will PM you. | |
| Phono rig capacitance Al, thanks for pointing out those details. You are right. I had not looked at the too little side. On the correlation I would hope so, it would make things easier but there in solid convention for quotation that would make it easy to figure out, b... |
