상품특징
One amplifier can used wiht tube EL34, KT88 or 6550, so, you can get 3 kinds of sound from different models tubes. The default matching tubes of this machine is KT88. If you need another 2 new sets of tube, please purchase in addition. There is a Red selection button on the Back of the amp to switch.Pure hand-made, the whole machine is welded with scaffolding.Can be used as an Integrated amplifier, power amplifier or Headphone amplifierTriode and ultra-linear selection are available, which can be switched by the button on the amplifier. With a remote control,Vacuum tube protective cover,Fuse and an English manual.We recommend that you spend 100-300 hours to RUN-IN this amplifier to get a better sound. Generally, you could get a better and stable sound after 100 hours, and you could get the best sound after accumulating more than 300 hours.
상품설명
Features Pure hand-made, the whole machine is welded with scaffolding. Use a square power transformer specially developed for this machine. The output transformer uses two high quality wideband EI output transformers. The voltage amplification and boost stage uses a 6SN7 for power supply filtering. The voltage amplification stage and the push stage use two pairs of 6SL7 and 6SN7 tubes, respectively. The rear stage uses four KT88/6550/EL34 tubes for class AB push-pull power amplification. Triode and ultra-linear selection are available. External independent BIAS-ADJ current display header. External EL34/KT88 tube selection function, easy to replace different types of tubes, adding endless fun. Infrared full-featured remote control. Use thick silver plated signal leads. With pure post-level function, it can be connected to independent preamplifier signal input. Power on mute delay function (about 30 seconds). Select Japanese ALPS high-end motor potentiometer. Easy-to-install plug-in tube shield. Product parameters: Frequency effect: 10Hz 40kHz (+/-0.5db) Total harmonic distortion: 1% (1kHz) Signal to noise ratio: 91dB Input sensitivity: 380mv (when Integrated amp input) 820mv (when pure power amp input) Input impedance: 100KΩ Output impedance: 4Ω, 8Ω Power supply voltage: 230V ± 5% (50Hz/60Hz) ~ 115V ± 5% (50Hz/60Hz) Machine volume (400*203*390) (W*H*D) mm Use vacuum tube: 6SN7*3.6SL7*2.KT88*4/6550EH*4/EL34*4 Power consumption: 310W Net weight: 26kg Rated output power: 25W+25W (RMS triode working state) 45W+45W (RMS ultra-linear working state) (KT88) 25W+25W (RMS triode working state) 40W+40W (RMS ultra-linear working state) (EL34)
