A classic MC boost transformer. With 2 input systems, the impedance can be switched between 3-40 ohms, and a PASS line is included, so you can freely enjoy various cartridges and tone arms. There is a feeling of use such as scratches and dirt (Takasaki Atsushi)
Maintenance information: 2025.7.8 operation confirmed
Accessories: none
Main specifications: MC boost transformer input 2 systems switchable, primary impedance 40 ohm, 3 ohm switching, secondary impedance 4 kΩ boost ratio 1:10 frequency characteristics 10 Hz to 100 kHz, W97 x H65 x D155 mm 0.8 kg
The price has been reduced. 2026/1/14 sales price 18,000 yen. Currently sold. Popular connector-type MC step-up transformer. It uses an ultra-compact double voice coil, and although it is small, it boosts the voltage well. A powerful machine that lets you hear realistic sounds. It can be used for a wide range of purposes, from SPUs to MC cartridges such as DL-103. In addition to the exterior and bald paint, you can see a feeling of use such as dullness, abrasions, etc. (Kobayashi Hitoshi)

Main specifications: boost ratio 26 dB adaptive impedance 3 to 40 ohms frequency characteristics 20 Hz to 30 kHz W13 x H13 x D55 mm 20.8 g
*Currently sold. Audio-Technica step-up transformer. The left and right independent transformers are shielded with a permalloy case. Impedance can be switched between 3, 20, and 40 ohms. The fact that it is equipped with 20 ohms is a nice point. There is a feeling of use such as dullness (Murakoshi Yoichi)
Maintenance information: 2026.2.1 sound output confirmed
Accessories: none
Main specifications: MC switchable step-up transformer, primary impedance, 3/20/40 ohm switching, bypass possible, dimensions W110 x H65 x D150 mm, weight 920 g
Maintained! L type with reinforced shields from the Danish famous Trans JS No. 6600. Since the boost ratio is high, the weak point where it is easy to pick up hum is overcome with a strong shield. Ideal for SPUs and older MC series with poor output, the rich tone is exquisite. There are small dullness scars (Sasaki Shota)
Maintenance information: 2026.2.6 Maintained (The PASS/ON changeover switch was causing poor contact. The inside was opened, the changeover switch was disassembled, the contact part was cleaned with a contact cleaner, and contact grease was encapsulated to eliminate poor contact. In addition, the input/output RCA terminals were polished and cleaned. Also, since the rubber feet were missing, they were newly repaired. (Currently, there is no poor contact between each output terminal and changeover switch, and switching operation is good)
