Thank you for viewing! This is a kit for the early model of the Famicom, which allows for easy AV conversion, video output, and pseudo-stereo modification. AV cable is already attached. The dimensions of the product are 25mm (length) x 36mm (width) x 12mm (height). After the product is made, its operation is confirmed using a Famicom dedicated to testing. You can enjoy a clear image and thick sound with a stereo-like feel from left and right. For installation, a soldering iron and solder are required. Please proceed at your own risk. A manual is included. Also, when purchasing, please confirm whether your Famicom is the early or late model. The early model does not have the FF mark on the front label, and the late model does. Before shipping, we will perform another operation check after purchase. Please refrain from purchasing if you are concerned about minor imperfections. Also, because each item is handmade, the product may slightly differ from the photos. * When using video output, vertical stripes may be slightly noticeable due to the clearer image. There is a way to reduce this, so please inquire if you are interested. However, it is difficult and challenging if you are not accustomed to it.
