We have sold over 300 line transformers to date, and we are grateful to have received all positive reviews. Regarding line transformers, we mainly sell them as clones, but we are proud to say that we produce products with superior quality in terms of wiring technology and noise processing methods compared to the original products. Although the sale of manufacturing manuals seems to be increasing, they do not provide accurate cloning and noise processing methods. Therefore, if you are looking for quality that you can use with confidence on-site, please consider using our products. This is a transformer box inspired by Cafe au Lable's Amateras. Although it has a narrow body, the performance is the same as the original size. This is a clone of Cafe au Lable's Amateras0001. We have received positive feedback from those who have purchased it, and we believe it has been faithfully reproduced. Please refrain from purchasing if you are concerned about slight scratches or blemishes on the handmade products. The size is a more compact version of the Amateras0001.
