It is made to Cayin’s highest standards in a deep, glossy case with a headphone output and VU meters, a classic tube amplifier for a modern home.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/cayin-jazz-80-el34-kt88-bluetooth-tube-amplifier-photo-angled.jpg?v=1791382432\" alt=\"Cayin Jazz 80 tube integrated amplifier\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEight tubes, two modes\u003c\/h3\u003e\n\u003cp\u003eFour matched KT88 (or EL34) output tubes at the back provide the power. In front of them, two 12AX7s amplify the voltage of the incoming signal and two 12AU7s work as phase splitters and drivers for the output tubes, in a Class AB circuit with a rich, organic sound. A small toggle switch in front of the 12AX7s chooses Ultralinear (2 × 40W, dynamic and powerful) or Triode (2 × 20W, softer and more detailed). Cayin gave the Jazz 80 an elaborate power supply, including a filter choke.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/cayin-jazz-80-el34-kt88-bluetooth-tube-amplifier-photo-tubes.jpg?v=1791382435\" alt=\"KT88, 12AU7 and 12AX7 tubes of the Cayin Jazz 80\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eBias you can check yourself\u003c\/h3\u003e\n\u003cp\u003eEach output tube has its own bias trim potentiometer.
