HM-3 | Primary Series Connection
12R (7 ~40R) | 4,7K | 47K | 20x / 26dB | 58 x 52 x 55 | | |
| Primary Parallel Connection
3 R (2 ~7R) | 4,7K | 47K | 40x / 32dB | 0,5Kg | | |
hei
her er noe å lese om emne ,,,de er da det begynner å balle på seg
,men de ser ut som 40db+26db =høyt me tanke på 0,5 mV og step up er den som heter 12R,og nålen som du skal handle har 12 ohm
Disse 3 andre er nok bedre egnet til nål me 0,5 mV og intern impedans på12.
Mvh

The H-2326 is a special wound transformer using the core from the HM-3, but with less gain. | | | | | | | |

Part 2
What Is There To Understand Here?
Let’s imagine I have a 3 ohms internal impedance cartridge. What are the devices I should buy?
Some devices from this table have a 3 ohms setting: FRT-4, Denon AU 320, Denon AU 340, AT700T, Ortofon T2000, FR-X1L, EAR MC4. What we can see is that the natural impedance of these devices (respectively 37,3 - 36 - 43 - 18,7 – 14.9 – 11.8 and 52,2 ohms) can be separated in two groups: Some of them have very low natural impedance (between 11.8 and 18.7 ohms). I think these figures are really too low and will limit this kind of step-up for use with very low internal impedance cartridges (1-2 ohms) especially the Ortofon T 2000. The remaining step-ups have a natural impedance between 36 and 52.2 ohms.
We will consider this range as a good range for loading a 3 ohms internal impedance MC cartridge. The amplification ratios associated with these step-ups are between 30 and 36 (gain is between 29.5 and 31 db).
