Prince competitors of tenderness KT88 A single-ended tube amp tube amp

Perfect sound quality from strength and innovation ........ AK88 is a combination of art and sound quality, good taste, the pursuit of people level!

Original civilians, 6N8P push KT88 Class A single-ended tube amplifier, which lasted two months, finally shelves, the machine follows the American crew line, power amplifier stage by a pair of radio beam as four KT88 tubes, and then into a single-ended Class A work, the circuit has a super-linear connection and standard connection, as well as triode-connected free with wiring, the machine default Superlinear connection or a standard connection, the first stage voltage amplification still use the rich sweet taste of bile Name tube 6N8P two, SRPP connection, SRPP circuit in the audio preamplifier is a known larger circuit, which is characterized by high gain, low distortion, low output impedance, resulting in excellent sound quality. The tube amp output power is moderate, push 10-60W of bookshelf speakers, wide frequency response, high fidelity. Deep and powerful bass, highly penetrating, midrange performance, low sound quite thick, pure and beautiful timbre, strings, brass appear lifelike, homophonic full, mellow finish Naiting.

First statement: Machine image without any treatment, completely taken in kind, all real real shot, please enthusiast finds, do not blindly buy those with no background picture after PS machine after machine, gullible! In addition, some friends bought before the actual use of the machine, a little noise, has now been fully improved, changed the transformer installation, the machine is now no noise except the horn into the ears will hear a little bit! This question please rest assured purchase, ultra-high signal to noise ratio! Do not worry! ?? ??

Must-see before making the agreement:

Dear friends, when you photographed me this baby, you have recognized me this Agreement, please read carefully, first of all we are operating in good faith, 100 percent not flicker any one customer, this product have been strictly before shipment test and aging test, confident that there will not be any quality problems, but based on our country's situation, the express delivery industry regulation is not mature, moral courier industry is not very standardized, resulting in the quality of service is poor individual courier company , goods issue is easy to break, but we have to guard against a lot of effort, done a very good package, we can be confident that, recently signed a contract courier companies, all express orders are stamp Alipay words, Description Customers can first inspection receipt (inspection precautions 1. panel without obvious bump .2 tubes without obvious break or leak tube white .3 a seamless hair accessories). If there is a significant bump inspection and abnormal sound can reject the goods, but once signing receipt explain your transportation to express no objection, say some of the words have broken express feeble! Another particular note is that all goods quality problems will not be returned, some individual friends bored with the ground did not expect to return, which is very stupid! Stereo audio quality and a lot of factors, not how you buy a good effect can be achieved, while the sound quality of this stuff is subjective relatively strong, so the sound quality by anyone in any return, the shop will be rejected! You agree that this agreement can take my stuff, and if you do not agree then please look at Taobao other sub shop, in addition to a new tube of the machine, except for the new stock 6N8P tube pipe, the other half is the dawn of a new band warranty) their baby is also very good! thank the thousands of friends support shop!

Before publishing this machine, I want to say a few words Shaoyou more concerned about the topic, has recently been in order to sell their machines in this tube KT88 belittle performance and sound quality that people do not know a whole because KT88 tubes than EL34 and 6P3 and other tubes are several times more expensive, these people can not afford their own investment in small workshops, "could not eat sour grapes!" Really scared, you have qualified to say this classic tube is not good, the key point is that you can not do, even if done not out of good quality, which has a relationship with your personal level, at best, is only selling small machine ?? How many fans abroad in pursuit of this name and favorite guts! Chan fans with Taiwan's famous saying, KT88 tubes and EL34 is simply not a grade thing, the difference is not just the power difference, KT88 out the kind of mellow voice, EL34 is never done, the kind of fine and mellow people sound, refreshing surging deep bass, people only listened to deeply understand! Take people feel lousy Swans M1 for instance, and other machines with EL34 push, voice drifted where to go, the sound of thin, each enthusiasts can try, if you put this AK88 that you try again, immediate, so this speaker now alive! There practice have a say, on paper that can not compelling, it is recommended that hearsay evidence, the crowd of fans do not listen to those calumny, with the brain to buy things, not to follow suit, with the end does not fit your own!

Latest AK88 physical as follows: Improvement is:

1, the output transformer changed little cover, power transformers instead straddle installation, effectively put an end to the magnetic interference.

2, the internal circuit plus a high voltage delay, delay of 30-47 seconds, the effective protection of the tube, extending tube life!

3, rectifier tube into the dawn of small swallows 5U4G

4, scaffolding welding machine (if you are welding scaffolding friends need additional 100 new, scaffolding welding machine benefits to noise ratio, low interference, easy point grounding, the sound is indeed better than the PCB of machine details, go inside line can take the closest, PCB can not do, and easy maintenance in the future!)
