6SL7: 6N9P, 6H9C, ECC35, 6SC7, 6CY7. 6SN7: 6N8P, 6H8C, 6H8M, 6H8J, CV181, QB65, ECC32. 274B: 5Z3P, 5BX1, 5U4C, GZ30, 5Z4G/GT Features X9 tube power amplifier is purely hand-made, whose main circuit uses scaffolding welding, high voltage power supply and filament power supply independently use two imported Z11 iron core high efficiency power supply transformer, output using two imported wide frequency response EI type single-ended transformer, advanced winding weaving technology brings better sound separation, frequency bandwidth, full sound field, delicate sound and strong power. High-end vacuum tube combination fo better sound performance: adopting 2PCS 274B tube as rectifier, front stage uses 2PCS 6SL7 and 2PCS 6SN7, and 2PCS 300B tube as power amplification, the tone is full and delicate, the analysis ability is good, the dynamic is abundant.
And with design of high-voltage delay when turn on and silent delay (30 seconds) circuit. With 6 groups of signal inputs (MM phono, LINE1, LINE2, LINE3, XLR BALANCED, PRE IN), it means that it can be a integrated power amplifier, a MM phono amplifier and a pure power amplifier, specially adding the function of balanced output to satisfy more audio devices, and switchable input voltage is convenient to use in most countries. Adopting high-end components such as Japan ALPS potentiometer, Germany Mundorf capacitors, copper foot five-color ring high quality resistance of 1% accuracy and so on. Independent grounding technology is used for pure tone and original sound, and support 4/8/16 ohm speakers. Specially designed high-gloss VU meter and switch knob, plug-in vacuum tube cover which is very easy to install, adding power tube bias current adjustment function and power output level meter sensitivity selection.14mm aviation aluminum chassis, exquisite appearance with vintage feelings, bringing both the auditory and visual enjoyment.
