Hello visitors and buyers,

Welcome to Queenway store!

 

    About the products details, there we carefully tell you: these specifics produced by AliExpress system, some of these are not correct or even wrong. So the correct products specifics is from the detailed description. Usually the description has some pictures and much words. And if you are in 110V rear. Please notice the items input voltage. As we can not mark it on few items.

    About the international shipping/transportation fee, if the shipping fee is expensive, please contact us. Sometime we can find some cheaper shipping way and we will 100% reply to you! Please carefully check the packing/box/parcel when the sender see the goods. 

 

 

                                                                           

 

 

The main factors affect the sound quality of vacuum tube amplifier

1. Single-ended and push-pull circuit

At the end of the power amplification, amplification of push-pull is easier to get high power output, because push-pull is a vacuum tube amplifier "+" signal, a vacuum tube amplifier "-" signal, and then superimposed, so large distortion. Single-ended amplifier is a vacuum tube amplifier "+, -" signal, does not need the signal superposition, therefore less distortion. The sound Single-ended than push-pull good, especially in some minor details. However, Single-ended is difficult to obtain high power output, with vacuum tubes of the same type, Single-ended can do 10W, while push-pull is easy to do 30W, Single-ended to obtain large power will have to pay more price.

2. push-pull end power amplifier of vacuum tube different connections

push-pull the end of the power amplifying vacuum tube usually have three connections: triode form, super linear form and standard form. Theoretically speaking, the triode form by minimum distortion, output power is minimum; standard form get larger distortion, power is also the maximum; between super linear form between.

3. Affect the power transformer and output transformer of sound

High quality vacuum tube amplifier inseparable quality transformers, power transformers currently technically no trouble, the output transformer is the decision of the vacuum tube amplifier sound quality is the key. Because regardless of the output transformer selection is good, how sophisticated technology, both methods exist to avoid leakage inductance and stray capacitance components, resulting phase distortion. Output transformer as inductive element, to the transmission signals of different frequencies have different inductance. Therefore, the output of the transformer will be different in different voices lead. No high-quality output transformer, other aspects of the production of better quality vacuum tube amplifier is also meaningless.

 

Cayin A-300BMKTube amplifier 2x8W Tube 300Bx4 have all-powerful power match 90~270V

1. Using a special high-quality wide frequency response EI type output transformer,

2. Using a special toroidal power transformer,  

3. High voltage rectifier uses two Russian SOVTEK 5AR4 tube.

4.Pre-amplifier and grade were used to promote 6SL7 and 6SN7 tubes each two..

5. Post-amp uses two FULL MUSIC 300B / 300B tube dawn to do a single-ended Class A power amplifier..

6. Provide NFB selection function: 0dB working methods, suitable for large scenes, large dynamic music; -3dB Works for voice, string music..

7. External 300B noise adjustment (HUM BALANCE) function.

8. External independent BIAS ADJ. Adjustment and monitoring functions BIAS table and keep the best state power vacuum..

9. The full-function infrared remote control.

10. After the stage with pure function.

11. With the starting buffer function (about 30 seconds),  

12. With power and memory function.

13. The use of a thick layer of silver-plated signal leads.

14. Easy installation of plug-type vacuum tube shield.
