Producto en buen estado. Muy bien manufacturado. A pesar de ser un amplificador de solo 3 Watts de potencia su sonido es espectacular. No requiere ningún aditamento especial para su funcionamiento, solo conecte y disfrute.

届くのも速くアンプICも本物で商品に問題点はありませんでした。 当方、改造目的の購入だったため基盤のランドが商品画像と異なり小さく残念… ミュートのパターンは切断できますがカップリングなどは外付けとなります

These worked well. Bought a few as I wasn't sure if they were going to work at all and for the price I figured I'd give it a shot. Not an easy way to control the volume hence the 4 stars

الطاقة التى تحتاجها الدارة ربما تكون تقريبا على الاقل 3 امبير للحصول على صوت عالى بدون فقدان او تلف فى جودة الصوت
