CK300 is a single-ended high-power split headphone amplifier designed by Raphaelite with a direct heat pipe 300B as the power tube. The design is positioned for high-end headphone use, from the design to the materials used to achieve the best sound quality effect as the goal.
The both balanced and 6.3mm Jack output's impedances be adjustable by potentiometer between 32-120-300-600ohm
Full coulped output transformer make best combinaison with 300B tube, without use coulping capacitors, give a best orignal sound
Long research for the amplifiers design, give a vintage but modish look, high quality print
Separate power supply section give a best noise isolation from power part
Tubes used damping system
Offer a phono output to connect your vinyl player
Fully dote preamplification RCA and Balanced output, offer a ture preamplification system
The electron tube regulated split power supply has a moderate start function, making low noise possible; with multiple headphone impedance output and achieve a consistent output frequency response and consistent sound quality performance under multiple impedances. To achieve this function, it took two years to develop this complex structure of the completely coupled transformer, which is the core of the 300B headphone amplifier.
Standard output four impedance selection and the use of relay switching, impedance essentially covers most of the headphone impedance use. This machine split bile voltage regulator and electronic tube damping system, housing shielding structure, so that noise control to late night listening can ignore the interference of noise.
This machine has unbalanced and balanced dual input options, and the output ports have been increased to three, making it easy to use in different applications. This machine follows the classic style of the Rafale gallows, the appearance of antique and elegant. The production of this machine is believed to get more discerning headphone enthusiasts praise. It will also be the best match for high-end headphones.
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
