The parameters of KT88 and 6550 are the same. The tube has a straight shape, rich sound, open sound field, natural and smooth, and is the ceiling of a medium power tube. The reputation of 6550 is even greater abroad.
EL34 small family jade type, with lower power, this tube is nicknamed "One Generation Wind Style", with a sweet, smooth, delicate and soft tone. Renowned by European and American masters as the 'sweet and gentle voice', reproducing the 'heavenly sound'
Product Introduction
Adopting dual bile rectification, pre bile stabilization, inductor+2 large pond capacitors to form CLC type filtering, imported resistors and military grade Dahongpao resistors, German WIMA or German ERO, Siemens Qianceng Gao and other capacitor coupling, and American SPRAGUE as cathode capacitor.
The panel is made using aluminum alloy wire drawing technology.
The chassis and cow cover are both made of 1mm thin steel plate, with good shielding effect and sprayed with high-end wrinkle paint technology.
The 4-channel input adopts imported silver contact relay switching, which has a longer lifespan and lower contact resistance.
The input interface adopts a gold-plated lotus seat, and the output terminal adopts anti oxidation amber gold-plated terminal posts.
The signal line inside the machine adopts imported PTFE silver plated shielded wire, which has good sound quality
The power supply is 185W, using E1 N or large ring N, imported iron core, oxygen free copper wire winding, and sufficient power supply. The output cow adopts 0.35 thin imported iron core 76.2 * 25, and oxygen free copper wire is wound in layers and sections.
The power supply and two output cows are all sealed with expensive epoxy resin, which can provide functions such as fixation, moisture resistance, insulation, and thermal conductivity.
Electronic tube configuration (free upgrade from 6N8P to 6H8C from Russian OTK):
KT88 type: Shuguang KT88-98 * 2, Russia 6H8C * 2, 5Z4P * 2, WY-2P * 1
Type 6550: Dawn 6550 * 2, Russian 6H8C * 2, 5Z4P * 2, WY-2P * 1
EL34 type: Shuguang EL34 * 2, Russian 6H8C * 2, 5Z4P * 2, WY-2P * 1
Black laminated wood and metal seats for electronic tubes are randomly shipped, and the pictures are for reference only.
Remote control can achieve functions such as volume control, channel switching, and mute.
The volume adopts the original ALPS motor potentiometer from Japan. The volume knob adopts a high priced aluminum alloy solid core knob.
There are headphones to monitor and amplify the output. Inserting headphones will automatically disconnect the speaker, and unplugging will restore it.
The panel design has an equal loudness switch, which can be pressed to increase high and low frequencies at low volumes, compensating for the sharp sinking of the auditory curve at both ends of the human ear at low volumes.
This device has a memory function to remember the channel status when it was last turned off.
When turned on, the motor potentiometer automatically turns left and returns to its original position, and then automatically turns a small angle to prevent damage to the equipment caused by excessive volume.
When turned on, the channel status window flashes, reminding that preheating is in progress. After preheating is completed, it turns on normally and displays the current channel.
Press the mute button on the remote control, the channel status will flash, press it again to restore, or press the volume up and down button to restore playback.
