Excellent sound effects, easy to install, 6J1 tube pre-amp board kits. The 6J1 tube pre-amp can be connected to the sound source and amplifier to effectively filter digital flavor. The Eight 470UF Capacitor Filter is very clean, excellent power system lead to no hum, and the filaments are powered with DC 12V and need to be connected in series in order to reduce noise. The CouplingCapacitor has high frequencies and low resistance. If you want to use no plug AC 12V transformer, you need to weld the power line on the circuit board. It doesn't work if you can't use DC power input. The kit comes in parts so you can build your own tube amplifier.
👤I didn't use any of the generic components that came with the kit. It was bought for the board and sockets. There were cracks at a couple of pins in one of the 6J1 tubes. It lost its vacuum because of the act of sockets. I have a lot of spare and matched pairs. There is a The board is of good quality. During lead-free soldering, the pads were not de-laminated. If you're looking for a cheap project, this might be it. All the components that need quality control or precision will be replaced. Before soldering and applying power, you should test everything.
👤I like that it works once it's together.
Sidetone- Sidetone control allows you to change the sound of your voice in your headset. In to your friends. Douk Audio P1 Preamp has been acclaimed by countless audiophiles worldwide, now they upgrade 6J5 to JAN5654 / GE5654 tubes according to their feedback, the sound quality will be greatly improved. P1 can be used as a HiFi tube Preamp, ausb DAC or a headphone amplifier with HiFi clear, warm, dynamic, sweet tube sound, bringing extremely high-quality sound. There is a support for APTX-HD lossless transmission in the qCC3034). Matching well with many audio devices such as iPod, Phone, MP3 players, TV, Blu-ray players, and CD players, the PC-USB is compatible with Windows/Mac/Linux system. The NE5532 opamp+classic 47 headphone amplifier architecture can drive headphones with a sound quality of up to 300 hertz, and a bypass switch is specially designed to turn on/off the tone control, more convenient to enjoy original sound or obtain more delicate sound with a bass control knob The blue and orange light decorating vacuum tube is very suitable for home and desktop audio systems.
👤This is based on my initial impressions of the item. I'm impressed. A great sounding amplifier. It was very well made. There were no complaints about the quality of construction. You don't know what you're going to get with this price range. There is a The bass and treble controls add to the P1's usefulness. I think they're analog. When they're set flat and then taken out of the signal path, I don't notice a change in sound quality. Having the ability to remove them completely is a plus. Even with the stock tubes, this sounds great. I have two things on hand for comparison. I've had a iFi Zen DAC as well. This little gem is better than all of them. It is more open and multidimensional. Better dynamics. It's just so sweet. There are tons of volume available. I like volume levels in real life. If you're on the fence about this, place the order. If you regret it, I will be shocked. I have done 2 tube upgrades since getting this. Riverstone Audio matched GE JAN 5654w and Voskhod Rocket 6J1P-EV/6ZH1P-EV matched pair from Tonal Tubes. You can detail out the a** with the Voskhods.
👤You say I could have fixed my PC audio problems for $100? Digital audio coming out of the PC is inferior to analog, I have always believed that. I know this is mostly a matter of taste, so that is what I like. I like the sound of R2R and Vinyl, it has a warmth and depth that fills the room. The sound coming from the PC was not as good as I had been led to believe. I was skeptical when I bought it, but I decided to take a risk. I've spent more than $100 on software and other products to try and get the sound of my music right. I was a big fan of Winamp on the PC, but then I discovered R2R and high quality vinyl, and I couldn't go back. I used Stereo Tool and MusicBee to get a decent sound out of my Alienware R17, which was equipped with NVIDIA. I couldn't get the sound of the ONKYO surround receiver to be as good as the one I was connected to. This is a little amplifier. A small box has a small amplifier, 2 bulbs, power cable and ausb cable. How much change can this make if you compare it to the ONKYO receiver? I set up the bulbs, plug them in, start MusicBee, and then select the right output. The sound that came out was amazing. The speakers and receive are the same. No software, no tweaking the sound, just stream to the preamplifier via theusb. This is the best investment I've ever made. Can't tell the difference between this and R2R. Get one of these immediately.
👤The sound quality is good, nothing perfect, but it has a little noise in the sound, but it's made by my computer sound card. The Bass and Treble control is very useful, it works perfectly, and the volume button works very well. I loved the design and it adorns my office. The power button has a light on it. It also has three switches for choose tubeLED color, tone, and input. When the amplifier is on, the two tubes don't heat up much. The gold plated 3.5mm headphone jack doesn't work well with my headset. There is a I tested all the input options and found that theUSB is better than theRCA, but I can't use the computer's built-in cable to connect theusb to my computer. I'm using the RCA cable, but I'll use theusb if possible. I didn't see a big difference in sound quality between the two, but the only way to get the cable to my computer was with energy and video cables.
The maximum output power is 160mw.
The mini MM tube Preamplifier has an excellent appearance and strong structure. The NANYI XLR Cable can be used to connect a 3.5mm stereo to a device. 3.5MM and 3Pin XLR plugs are sophisticated and high adaptability. The plug housing is attractive and durable. The 3.5 MM plug is gold- plated. A hassle-free 18-month warranty.
👤Don't buy this product. The first time I bought this cable, it didn't work with any mics, so I returned it in exchange for the new one. The new one is just as bad as the first one. I need it for an interview tomorrow. This is disappointing. If could not give any stars. I would.
👤I had to sum a mono out into dual so the sound would fit in both ears of headphones. Didn't meet my needs.
👤The cord works. I use it to connect my recorder to the sound board.
👤It doesn't work for my microphone. It works with all the microphones. There is a fake period. Before buying, just consider. Don't think you'll regret it later. You will need a device such as X2u to work on it. If you want to connect to the laptop, it's better to buy the XLR to theusb.
👤This product was not the right one for my amplifier and keyboard. Will be back. Thanks for being prompt with your products.
👤Don't work at all. Maybe it's because I'm Mac.
👤It works if I position the cable in a certain way.
The C2383 triode power amplifier has a 6J1 electron tube. The audio signal can be used for various power amplifier boards.
👤It's not clear. I have never used a tube amplifier. I love this little guy, it gives a nice clear sound, separate instruments are well defined within a piece of music, it's a nice addition to a previously all digital system. There are blue leds under the tube sockets which make the tube light up blue, which is a matter of taste, but could be cool, but one of them blew out early on, I accidentally knocked the crap out of it. I used a soldering iron to cook the other led. I like it better now, with its faint orange glow. I will get more of these for sure.
👤A chunk of plastic is missing from one foot. One foot is missing. There was a screw missing in the corner. The sealed black bag did not contain these missing pieces. It's strange indeed. It was hooked up to make up for the broken case. But, no. Terrible distortion, it's useless. It was even switched to known good tubes. You can get the Audio Tube-01 if you spend the extra.
👤This requires a 12v AC (not DC) adapter. I made a mistake and the sound came through, but badly. I got an AC accessory. It sounded great. I was hoping for a big step change, but it was still an improvement. I swapped out the tubes for GE ones which were a big improvement over stock. I'm using an accessory to run my phone audio through headphones. It adds the tube sound so it's workable, but it reduces the output volume from the phone. I'm pretty sure this is the cheapest option to try. This is a pure tube preamplifier. I took the tubes out and didn't hear anything.
👤It is a very nice and cheap tube preamplifier. After burning the tubes for an hour, the unit came back with a great sound. I put the 6j1 that came with the unit on my Fosi preamp and it's been great, I tried a pair of 6k4 tubes and still great sound. You will be amazed by the price, do not panic. I am very happy with this product.
👤This product is not good. You can't turn it up all the way or even close without distortion. I ordered another one because I thought the first one was bad. Nope... Same outcome.
👤Nice for the money. I changed the tubes out with a Matched Pair of Tubes, which were from the same manufacturer. It sounds great on my turntable. Really nice.
👤It was connected to my amplifier. Have to turn it all the way up.
👤The presentation is amazing, but the product does not work and does not have a power source.
30.0 watt output The 6J1 tube pre-amp can be used to connect the sound source and amplifier, and it will effectively filter digital flavor, and the music and human voice will be relatively good. The Eight 470UF Capacitor Filters is very clean, excellent power system lead to no hum, and need to be connected in series in order to reduce noise. Matched transformer The AC 12V 0.8A vacuum electron tube valve preamplifier amplifier board uses DC 5.5*2.1 sockets and an AC 12V transformer, you can use it without a plug. You can enjoy the process of building your own tube amplifier with the Nice Kit, it comes in parts so you can assemble them yourself. Excellent Capacitor. The high frequencies and low resistance of the couplingCapacitor makes it a good choice for most times.
The TDA1308 is an integrated classAB stereo headphone driver contained in an SO8 or a DIP8 plastic package. The device is made in a 1mm process and is used for portable digital audio. The working voltage is 3V to 6V. The package includes a headphone amplifier board. If you have a problem, please contact them for a solution.
👤There was no bass in the load. I don't think they are large. There is a There is a loud pop on turn on.
👤I am resurrecting a broken Yamaha receiver. I needed a small module for my headphones. The requirements were met by this module. There is a The amplifier in the Yamaha isn't working. I'm modifying it with the installation of a Class D stereo amplifier module. The Class D amplifier uses floating grounds for the speaker output, so it can't output to the headphones. The jacks are common ground, this module worked great, I had to use a L7805 linear 5vdc regulator to power the headphones. The input of the headphones was connected to the Yamaha circuit. It worked well. The sound quality was decent and loud with a set of Bose headphones. There is a I was very pleased with this tiny module.
👤The output caps on this pcb are too small for headphones. You'll lose a lot of low-end in your audio if the cutoff is near 200Hz. You know how to solder if you buy this. Adding 100uF caps in parallel with the existing output caps will cause the cutoff frequency to move to 40Hz, which is lower than most headphones can handle. This product works well when you change it.
The kit comes in parts so you can build your own tube amplifier. Preamplifier adopt 6J1 electron tube. This amplifier can be used with a post-amplifier or an active speaker, or it can be used with headphones. 12V DC power supply, internal stable boost to 100V are used to ensure the performance of the tube. The general recommendation is 16-150 ohms for the headset. A cost-effective preamplifier with warm, mellow, sweet and transparent sound. The sound of the board is warm, mellow, sweet and transparent. Preamplifier is a cost-effective option. Plug the tube in the direction of the foot and you'll get a replacement op amplifier. The joy of doing is something this preamplifier can allow you and your family to experience. Stable performance, quiet and no noise is what the preamplifier tube board is for. 3.5 MM headphone output and a preamplifier output are available at the port.
👤It sounds good, first off. I just got it and listened for an hour. I was expecting the kit to be soldered together. You just need to put the tubes in, screw on the covers and plug it in. I had to put the tubes first and the acrylic after because the tubes were wider on the bottom. The tubes.12V ac adapter is not included, so I would have to take the acrylic off. I bought one from best buy and it was faulty. I have an old one. Japanese ac accessory. It still worked. This is worth it if you are interested in tube sound. There is a I tried it with a 9V ac adapter. The sound was intermittent. Make sure you get the right amount of power. There is a The electrical usage was checked with my kill-a-watt and the amplifier used less than 10 watt. It seems like class A because the wattage didn't change.
👤I love everything about this little device. The components are exposed by the case. I haven't been able to use it in conjunction with a power amplifier yet, but I did try my headphones and they sounded amazing. You can't go wrong with the price. Just buy it.
👤My husband likes the tube board. It doesn't come with a power source that's 12VDC. There is some assembly required. He made the tubes larger because they didn't fit in the holes provided. His headphones have improved the sound.
The kit comes in parts so you can assemble them yourself. Before the output level automatically switches to promote the headset or push the rear lm1875 amplifier, the amplifier without output should not be inserted into the headset. This product uses a tube to do an amplifier. The whole sound system can bring a sweet natural 'bile' if the tube buffer is reduced. The average is better listen. The use of a 6J1 fever tube gall bladder before the class is the pre-level. The tube increased by 10 percent because of the X-10D circuit principle design. The machine uses dual AC 18v input, so you don't have to worry about looking for high voltage power supply, and the board comes with boost to enjoy you in the low power supply. The power works like this: a power supply began to heat, then a boost from the zero voltage began to boost, and other tube filament hot, so this is the same with the bile rectification. The excellent power supply system will not have the exchange of sound, the power supply is 12V and there is a need for two tube filament. If the friends can accept this way, the output of the sound is slightly smaller than the digital sound source, and also the output of the product. The output function can be used after the amplifier. 30.0 watt output
👤My husband bought it for his Christmas project in 2021. The kit was easy to assemble. The heat sink is small and the cars run a little warm but not to the point of triggering auto protection shut off. The included tubes don't sound bad, but will try 5654 later. There are some things that need to be changed. I added more aluminum to the heat sink. A transformer with a 7802 is needed to provide DC current. The original circuit uses a drop Resistor on the +ve rail to power the filament. It sounds better after the power source is separated from the circuit. The ERO MKT1812 2.2uF caps were used because there was not enough space for the WIMA caps. This improves the sound. The kit is cheap and has a lot of potential. I was surprised that it wasn't discussed in the forums.
Stable performance, quiet and no noise is what the preamplifier tube board is for. 3.5 MM headphone output and a preamplifier output are available at the port. The 6J1 tube pre-amp can be used to connect the sound source and amplifier. Eight 470uf Capacitor. The eight 470UF Capacitor Filters is very clean, excellent power system to no hum, and need to be connected in series in order to reduce noise. A high Frequency and low Proof Capacitor is called a couplingCapacitor. You can use an AC 12V transformer without a plug, just need to connect the power cord to the circuit board. The kit comes in parts so you can assemble them yourself.
👤I went to put together the kit and it wasn't the right one.
👤There was a missing part. There were a lot of projects on the shelf. It was too late to ask about it when I checked it. The pot that was shaved worked as expected. It's a fun kit to assemble and the parts are in-spec. I probably got the part but I could have been in touch sooner. I recall it was shipped sooner than expected.
There is support for Moving Magnet and Moving Coil. The dimensions are 170mm x 60mm. 2 tubes. You need a transformer.
👤I am having issues getting signal through it, but it is probably my fault. It's difficult to hook up to this thing period. It's hard to work with the screw type, so I wish it had an easier interface to use. The power labeling is hard to understand. If I get it working right, I'll update. I'm playing around with my guitar and amplifier.
👤I have a solid state amplifier and a digital amplifier. I like the sound it makes. The hard edge is taken off digital. It has some amplification so you will need an input level control if you want the noise level to be low.
👤When running in front of a tube amplifier, it's very clean. I made a pedal out of a solid state guitar amplifier by adding a volume to it.
👤You need to turn on the channels in series and put a potentiometer at the output.
