This is a transformer box inspired by Cafe au Lable's Amateras. I have sold over 200 line transformers so far, and I am grateful to have received all high ratings. Regarding line transformers, I mainly sell them as clones, but I am proud to say that I produce products with superior quality in terms of wiring technology and noise processing methods compared to the original products. Manual sales of manufacturing methods are also increasing, but since accurate cloning and noise processing methods are not being performed, please use our products if you are looking for quality that you can use with confidence on site. Please refrain from purchasing handmade products if you are concerned about minor scratches or scuffs. This is a model that uses XLR terminals based on the Amateras0001. It is a model that expands the range of use with a combo jack input and two types of outputs (simultaneous output possible). It was created in response to requests to output without using a DI in live houses. (※Please note that the input impedance is recommended to be 1kΩ or less) ・Case: HAMMOND 112x60x31mm ・OEP transformer ・Wiring material: Oyaide single-core silver 0.5mm ・Solder: SS-47 ・Jacks: NEUTRIK balanced specifications If you are concerned about sound quality, please watch the comparison video with the original. https://youtu.be/I2w54vKCMUI There is also a comparison video with Lundahl. Please watch it. YouTube "OEP & Lundahl Transformer 2 Types Comparison" https://youtu.be/pNRHIy1CULg The Lundahl version is 18,000 yen for the 6.3mm phone jack specification and 20,000 yen for the XLR specification. If you pass a DC power supply through the transformer, the core, which is wound with iron wire, will become magnetized like an electromagnet, which will significantly impair the sound quality of the transformer. Magnetized transformers must undergo a special treatment called demagnetization. Absolutely avoid passing DC power, such as by passing phantom power or measuring the transformer with a tester. Note: Fake sites are increasing. The sites where we are selling are Yahoo Auctions, Mercari, Rakuma, and direct sales from YouTube links only. Please be careful.
