1.The whole panel is made of 14mm aerospace solid aluminum wire drawing. The knob is made of full solid aluminum high-gloss car. The signal switch on both sides adopts Japanese knurling technology, and the hand damping is very good. High-precision multi-function output power meter and ammeter, backlight black The bottom is specially made of film. The back of the dial is set with dozens of LED lamp beads, the double structure chassis base, the outer layer is laid with 3mm brushed aluminum plate, and the inner layer is made of 2mm thick steel plate.
2.The R100 power switch key is placed on the left side of the panel; the side knurling knob has built-in 4-speed dedicated functions, namely BIAS V1, BIAS V2 and METER H, METER L, to adjust the power tube V1, V2 bias current selection and level meter sensitivity. Damping selection. The right side of the meter head is the volume adjustment knob, which uses a high-precision ALPS potentiometer specially designed in Japan. The right-hand knurled knob is a 6-speed source input selection file, which are PHONO (single release), lin1, lin2, lin3, BALACNCE (balanced). ), PRE IN (pure power amp)
3.R100's high-voltage power supply and filament power supply independently use two Z11 iron core high-efficiency power supply cattle, the output transformer uses two Z11 iron core wide-band EI single-ended output cattle, all powered separately.
4.The R100 filter circuit uses 12 1500uf 600V Japanese Nichicon large hydrothermal capacitors and two specially designed chokes.
5.The R100 not only has the full analog amplification function of the vacuum tube power amplifier, but also puts the enthusiast's favorite vinyl singing function into it. The MM cartridge input R100 also has pure post-level function. The R100 has three sets of analog audio inputs, one group sings. Head input, a set of pre-stage inputs, and also a set of balanced input BALANCE ports, this is a true balanced input, R100 output has 4 ohms, 8 ohms and 16 ohms respectively, support all impedance speakers.

Tube Amplifier Precautions
1. 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.
2. 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.
3. Temperature is higher when tube amps working, placing attention to ventilation, cooling.
4. In the boot or just shut down for a period of time (within 30 minutes) Do not spill liquid on the tubes.
5. 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.
6. If you donot sure how to plug the tubes, please contact us before try it
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
