You will need to add a parallel resistor to lower (numerically) the load for your 1:10 SUT. http://www.hagtech.com/loading.html
Need a sut for Hana ml
I hava a Cary ph301 phono stage Mc has 60dB at 100 Ohms it’s to much gain for cartridge, I tried 1:10 into mm input , gain much better but it produced 470 Ohms sounds more like my Hana sl, the Hana ML needs >100 Ohms ,what ratio sut should I use ,any advise would be appreciated ,thank you ,and happy holidays.

Using a step up transformer with a turns ratio of 1:5 should give you a gain of roughly 13.98dB. The reflected impedance will be dependent upon the input impedance of the phono stage you are using. Many phono stages will commonly use an input impedance of 47K Ohms. If this is true in your case, your cartridge should see a resulting impedance of roughly 1880 Ohms. Here is a link to a calculator that can help you with the variables... http://www.mh-audio.nl/Calculators/StepUpTransformer.html Happy New Year! |
You lost me somewhere. You say the factory recommends a load of greater than 100 ohms. You also say correctly that your 1 to 10 SUT gives you a net impedance of 470 ohms. In other words, the cartridge sees 470 ohms when it looks toward the phono stage. According to the factory information you quoted, this is perfectly OK. 470 is greater than 100. What’s the problem? |
