| The correct internal-inductance of Windfeld cart.? If I have said anything technically incorrect i'll gladly accept corrections and apologize for errors I have made.dave | |
| The correct internal-inductance of Windfeld cart.? The main point you are missing here is that 20 times the voltage i.e. 6.8mV instead of 0.3mV into 47k pre-input-impedance, WILL and DOES 'pull' more current on the primary side which has ONLY 10 ohm impedance! A virtual short circuit!!I'm sorry, N... | |
| The correct internal-inductance of Windfeld cart.? Now to the current. A trannie like a 1:31.6 has a DCR of about 1.5 ohms on primary, and as we calculated 47ohm inductance and with a 13ohm in || a 10.18 ohm impedance.what is a 47 ohm inductance? Also the 10.18 ohm is only the resistive nature of ... | |
| The correct internal-inductance of Windfeld cart.? Hey Axel, Last part: Therefore "Current mode" means that the cart delivers the most current it can, into the SUT's primary and the best / most when properly impedance matched. I still don't get your "voltage mode, vs current mode" statements with ... | |
| The correct internal-inductance of Windfeld cart.? Hey Lew,In a perfect world, The SUT would be ideal and hence invisible to the cartridge and all loads of equal value would sound the same. Experiences Like Axel's just show how far from ideal transformers really are. I do not think any sweeping ge... | |
| The correct internal-inductance of Windfeld cart.? I think Axel is spot on with his comments and approach. I'm not quite sure I follow his distinction between "current" and "voltage mode" but maybe that is best for a different thread.Lewm wrote:I don't know of anyone else who uses a SUT and loads ... | |
| Platter Upgrade for Garrard 301 thomas.thanks for the link to schall and rauch. It made me remember the passion.thanks!dave | |
| Artemis Labs Ph-1 owners..... Hey Don,Are you using s step up now? It seems your #1 concern is noise and a SUT will help you address this problem since they can give "noiseless" gain. If you add a 1:10 you will increase your signal by 20dB which will require 20dB of attenuatio... | |
| Artemis Labs Ph-1 owners..... I have heard the artemis in two different systems with a number of different SUT's. The one thing i would warn against is going for more than say a 1:10 step up ratio unless you have a really low output MC (AN IO-J). We listened to some 1:20's and... | |
| Preamp gain question can you use the phono stage without using the linestage? If so, you could get rid of 31dB of gain right there.dave | |
| Preamp gain question The only thing I can suggest is to get a good feel for the proper gain structure you need and make system changes accordingly. From your last post you seem to be using something else for Phono, is this the case? Right now it seems you are adding a... | |
| Preamp gain question If the problem is too much gain, the solution is removing excess gain, not attenuation. Fix the problem, don't try to hide it.dave | |
| How do you know what to damp? Hey Jloveys,For your situation, I would probably trust Jan on this one since he has far more experience with the loading of his cartridge than anybody else. I have no idea why a SS, tube or OTL amp would load a cartridge differently. The SUT does ... | |
| Would Like To Hear From Strain Gauge Owners Slowhand/Mosin: when I posted my first post in this thread I had no idea that the SG device does not conforms according the RIAA standard, it was after a research when I take in count ( fortunately ) and share my findings: it was not exist a previ... | |
| Ortofon Per Windfeld Load Impedance? Hi Ralph, You mentioned it was easy to do above, would you mind going into more detail? I started a new topic called How do you know what to damp? and it would probably be best to post the method there.thanksdave |
