-Storage conditions: Temperature: -20 ºC ~ 70 ºC Humidity: 20% to 90%
Features:
-Handmade, using scaffolding welding
-Using two high quality and wide frequency response EI output transformer
-Using a customize Z11 core toroidal power transformer
-Amplification and drive part use SAR4 rectifier .
-Use 2X12AX7 and 2X12AU7 as amplifiaction,
-Use special high selected KT88 tube as push pull power amp lamp,providing switch for the triode connnection and ultra-linear connection modes.The triode connection mode is more suitable for the voice and the sound is more soft, delicat as well as nature. The ultra-linear connection is suitable for the big scence, the sound is more open and lively.
-It has a pure power amplifier ans it can conncet with an independent pre-amp's signal input.
-There is a power tube current control button and an electric meter dial.
-Infrared remote control function
-Power Mute delay function
-Selection of Japanese high-grade ALPS motor potentiometer.
-Easy installation of the plug-type vacuum tube shield
Tube Amplifier Precautions:
-Tube amp must connected with speakers before turning ON. Strictly prohibit send signals to amp without connected loads(speakers) or load short circuit when the switch is ON.
-Too high or too low power supply voltage does irreversible harm to the amp,preferably less than 5% of the specified voltage. If your mains voltage exceeds this value, often best to use with the AC power supply.
-Temperature is higher when tube amps working, placing attention to ventilation, cooling.
-In the boot or just shut down for a period of time (within 30 minutes) Do not spill liquid on the tubes.
-You should take about 100h time to operate the amp. RUN-IN to the amp gives it's best and stable sound.so during the first 100h use time the sound maybe is not the best, you can also use your own run-in method.
-If you donot sure how to plug the tubes, please contact us before try it
Speakers connection
-All tube amplifier used with stereo mode: L(left) and R(right) speakers.
-Normally there are 6 speaker cable connectors: +8L, +4L, -0L, -0R, +4R, +8R
-Example: +8L and -0L are for connecting with your Left 6-8ohms speaker
-0R, +4R is for connecting with your Right 4ohms speaker
Tube amplifier guaranty :
-Tube amplifier Guarantee: 6 months for tubes sold with amplifier, 1 year for the amplifier and PSVANE tube
