Pay attention to version differences when placing an order:
4Th Standard version :Developed by the 4Th Standard version Taiwan team, it has been changed to a green light version and circuit board, upgrading the bile duct to make the sound warmer and cleaner.
5Th Upgraded version :Developed by the 5Th Upgraded version Taiwan team, upgraded the gold-plated circuit board terminals, upgraded capacitors and resistors, and greatly improved sound quality.
6Th Flagship version : The 6Th Flagship version has undergone a comprehensive upgrade in appearance, with the volume adjustment button placed in the front and the wiring post placed in the back for more convenient use. It has added an additional set of inputs and added a black technology purification system. For the first time, a customized one-to-one bile duct has been added, and the upgraded circuit board and components have undergone user feedback and continuous trial and error. At any cost, we have developed a sound that can achieve more than 90% of the original version, constantly breaking new definitions. The strongest version has been launched.
Introduction to KT88 Electronic Tube:
The Orsefon team tested various brands of KT88 tanks, but still unanimously agreed that the original factory sound of the Mackintosh is warmer, and the large dynamic output is not disorderly and has a stronger sense of hierarchy. Therefore, they spared no expense in making a one-to-one replica, with a structure completely identical to the original Mackintosh factory.

The KT88 series beam power quadrupole has an anode maximum dissipation power of 42W. In audio amplifiers, two electronic tubes can achieve a power of 75W when used as AB1 push-pull outputs, and KT88-T can also be used in electronic voltage stabilizing circuits. KT88-T is similar to 6550 and can be used interchangeably.
