Are you afraid that there isn't enough power for tube amplifier?

Are you afraid that there isn't enough power for tube amplifier?

Sometimes audiophiles are afraid that there isn't enough power for tube amplifier? Now, you don’t be afraid of it. If there is a tube amplifier with output power up to 2 x 50W, that will be ok.

It is a mono-block integrated tube amplifier with 2 x 50W high output power with high cost effective, which is made of pure tubes, adopt 2pcs 12AT7 plus 2pcs 6N8P to drive 2pcs FU13, and its recrifier adopt tube 5Z4P.

Tube FU13 belongs to antique one and is equeal to tube 813, which is a direct thermal beam shot tetrode with thorium tungsten cathode, graphite anode. In the radio equipment, it can be used for the oscillator power amplifier tubes, and its using frequencies are up to 30MC. When it is used as a power amplifier (such as Class AB), its output power is up to 300W or above, it is high reliable, excellent linearity, and not only does it perform tigers’ roaring and thunder exhaustive, but also can perform thin piano voice with detailed and delicate, it is the master of tube amplifier.

FU13 sound is very good, power and life are outstanding, air sense and sound field is far better than with that cannot be compared, you may not want to listen to small power output tube after listeningFU13.Due to its high power output, it can drive high power speakers that tube amplifierwith lower output can't drive.It is the first choice to drive low-sensitivity, high-power and high-end speaker.

Enjoy DIY if you need customize your parts?

 Enjoy DIY if you need customize your parts?

Audiophile‘s DIY is a fun, but also is an attitude to life. You can DIY, get your unique product, rather than a mass-produced production. When your unique design by DIY and ultimately, that is how happy thing ah!

But sometimes no all DIY ideas can be realized, such as lack to some critical equipments, and these devices are basically large, expensive ... or local manufacturers provide only high-volume production, who cannot make single one or small quantities of customized production based on your requirements can be. For example, when making or DIY tube amplifier, often the holes are opened on the top plate, frankly to say, this job, if without the special equipment to do, it may be a difficult task. Or you want to make the holes on a pure copper, which is more difficult to complete.

However, these seem more difficult to do, now it can be more easily accomplished. We now introduce such a customized service to solve the problem that quantity from one piece.

You just need tell us your requirements with your drawing, we may accept 2D or 3d format, CAD (2D) format drawings like as dwg, dxf, pdf include parts precision tolerances, surface treatment and other special requirements or processing equipment. CAD drawing format; 3D model formats include Sldprt, step, igs, stp, x-t, prt. And, parts’ material may be aluminum, copper, stainless steel, or plastic.

Through pre-sales communication, we have an offer for you. After you complete online payment, we quickly complete your order until delivery.

HIFI Preamplifier with 3 Ways Active Electronical Crossover Linkwitz-Riley Filter

HIFI Preamplifier with 3 Ways Active Electronical Crossover Linkwitz-Riley Filter

Although many audiophiles put a lot of money and efforts to preamplifier, unfortunately they may experiences a little frustration in final output. It is hardly difficult to solve this problem to use excellent pre-divider circuit of preamplifier plus multiple power amplifiers, our series of electronic crossover board and amplifier board can perfectly realize your dreams!

There is a  HIFI preamplifier with 3 ways electronical  crossover，whose PCBA is refer to the ESP company by US, which is set to six-channel stereo output structure to output left and right channel stereo signal, this is, output treble of left and right channel, midrange and bass of left and right channel, you can directly connect it with 6 channel amplifier circuits then drive your HIFI speakers. Pre-electronic crossover ensures original and natural sound through separated frequency of pre-amplifier small-signal, then drive power amplifier directly to push speakers, allowing you to enjoy the atmosphere of the studio's site.

Crossover PCBA is constituted by renowned Linkwitz-Riley filter. Linkwitz-Riley filter, mainly for the active filter circuit, for example, it is used in many sophisticated multi-way electronic crossover systems. The characteristics of this filter is up to 4 stages attenuation slope, in other words, every one octave frequency sound energy will be attenuated 24dB, i.e. attenuation slope of -24dB / Oct (Oct ie Octave, an octave interval of the mean). Meanwhile, in the entire audio band (20Hz-20kHz), Linkwitz-Riley filter has a very flat phase response, which is far better than Butterworth filter after filter signal, no phase distortion, which is widely admired by audiophiles.
