Lundahl silver mc-transformator

to work successfully with low output moving coil cartridges. . I use the LL 1681 wired for 1:13 gain, and friends who also tried 1:26 gain, told me that using the higher gain you lose a tiny bit of definition, but nevertheless, 1:26 is usable, when necessary. The distortion produced by audio transformers is of a completely different nature to that produced by a transistor amplifier. . But - and this is a small "BUT" - the LL 1681 has a bit less transparency in the midrange and treble than the Jensen. To increase the copper filling factor, the "thick" wire is made of several windings parallel.

Do not measure the coils with analog or digital ohms meter or digital LCR meter. This is a transistor or op-amp amplifier which raises the output of moving coil cartridges up to moving magnet level. . For any zero feedback concept it gets spoiled this way, and once the signal is mistreated, it can not be made undone. So, it would seem logical that a cartridge with an output voltage of, for example,.5mV, when used with a step-up transformer with a 1:10 turns ratio, would produce 5mV at the transformer's output. .

While the LL 1681 is world class, but still cheap to buy, the LL 1933 is considerably better, but has its price. Transformer loading, the idea that optimum performance comes from matching the impedance of the load to the cartridge's impedance (shown above to be somewhat hit-and-miss) also gives rise to another fallacy that of transformer loading. . The LL 1681 sounds very neutral, like the Jensen does, but it has much better defined and textured bass.

New Lundahl moving coil designs, when I heard of new moving coil designs developped by Lundahl, I became very interested. Step-up transformers for moving coil cartridges are the most esoteric and misunderstood items in the world of hi-fi, and this partly explains why bilprovning uppsala they are so seldom used. . The reasons for the matched impedance myth are examined below. By default it breaks the ground loop. Amorphous, oFC 43x29x22, premium, lL1931Ag 8,.
