Maintained. This step-up transformer is cased from Jorgen Schou's No. 7351 transformer with red dot cap, which is familiar from orthophones. It's a pretty big boost of 177 times the boost ratio. It is suitable for cartridges with an output of 0.25 mV to 0.5 mV. The DL-103 makes an extra thick sound. It is also recommended for those who have Ortofon MC Cadenza etc. You can see a feeling of use such as appearance, dullness, scratches, etc. (Kobayashi Hitoshi)
