| The correct internal-inductance of Windfeld cart.? Axel, No one is arguing with your logic, and I am not foxed. I will leave it to Dave (Intactaudio) to comment on the second half of your post. Dave knows more about transformers than both of us. I did learn something from your story, so thanks. | |
| The correct internal-inductance of Windfeld cart.? I learned something. To paraphrase Gertrude Stein, a SUT is not a SUT is not a SUT. | |
| The correct internal-inductance of Windfeld cart.? Thanks very much, Dave. I bookmarked that thread for future reference. But in your experience with primary vs secondary loading does it often occur that the optimal net load for a given cartridge, when you load the primary of the SUT, is radically... | |
| The correct internal-inductance of Windfeld cart.? I really think it's quite interesting and unexpected (to me) that with pre-loading of a SUT, the optimal impedance for the PW seems to be about 10 ohms net, whereas, as you say, without the SUT the PW seems to like 500 to 1000 ohms net. I am not c... | |
| The correct internal-inductance of Windfeld cart.? Axel, Now it is YOU who have misunderstood ME. You wrote, "So, the SUT secondary "sees" the 47k input-impedance of the phono-pre! If you put -another- 47k R (as you implied)". No, I did not mean to imply nor did I think that you have two 47K resis... | |
| The correct internal-inductance of Windfeld cart.? Sorry, you are correct about my math error. 470 not 47. Much better. Your findings as to the sonic differences between loading the PW with NO trannie vs loading it either on the primary side or the secondary of a SUT are quite fascinating, and I d... | |
| The correct internal-inductance of Windfeld cart.? Axel, After I made my post, I re-read yours, and I realized I had slightly missed the point of your question. You might want to read the "white paper" on the Jensen transformer website, where they cover the complex issue of loading very well and d... | |
| Technics SP 10 Mk II a Albert, I am jealous that Bill installed fancy diodes in your Mk3. I may have to do it for myself in my Mk2A. But I am glad you are happy. Bill is a great guy, besides being supergood at what he does. (I see now that we both used the word "super" ... | |
| Technics SP 10 Mk II a Jax2 named a bunch of boutique film cap-makers. You only need to replace the electrolytics, not the film caps unless there is a specific problem. This is because your tt is pushing 30 years old, and this is beyond the normal life span of an electr... | |
| 2 turntables and one phono stage - Can I??? Almarg, I was in a way responding to the (good) point that you made. To do this properly, you need to isolate the lead carrying the "ground" side of the cartridge output (which as you correctly state is merely the other side of the coil from hot) ... | |
| Technics SP 10 Mk II a --Reliable? Repairable? Many if not most of the ICs in either a Mk II or a Mk2A are "unobtainium". You are no better off with a Mk II vs a Mk2A in that regard. Some have said that the MkII is more reliable than the Mk2A, but I have never seen an explanation for that cont... | |
| Anyone have any experience with the Naogoka MP110? It's not merely a matter of using the correct VTF. You also need to consider the effective mass of the tonearm. Somewhere in the lit that goes with your tt, Music Hall may reveal the figure for your tonearm. With a high compliance cartridge, you w... | |
| Anyone have any experience with the Naogoka MP110? A lot of this has as much to do with compliance as with "ride height". An MM, like the Nagaoka, will tend to have a high compliance. This translates into bottoming out on warped LPs, if the tonearm mass is not helping to damp the action of the can... | |
| The correct internal-inductance of Windfeld cart.? Axelwahl, You originally asked about inductance, not impedance. This naturally led some people to ask why you wanted that information, since the proper loading of your cartridge is easiest to calculate based on the square of its turns ratio of the... | |
| Raven One Motor Noise Problem Ebm, Apparently you have never read Edgar Allen Poe. (Could not resist the opportunity for some levity.) |
