This is another great product from Microwavemont!

Very high quality, and very well thought out. I bought the radio in order to learn more about SDRs and how the work. The board was carefully packaged, along with some origami, which is always a favorite!

I alway appreciate the thought, time and effort made by Microwavemont when he releases a new product, and I hope to continue to do more business in the future =)

Thank you!

A very satisfying new generation NUTUBE DAC/AMP.

For Nutube headphone amplifier/NEX HR

When I received the product, I was very impressed with the origami of the Korean flag.

The sensitivity of NUTUBE is good, so white noise is mixed to some extent, but it can be ignored enough.

The sound is very warm, powerful and soft. Build quality is also very good.

The seller 's response was also very friendly and impressed.

In short, this product is the best product to experience NUTUBE inexpensively.

Very nice sounding amplifier and DAC

For Nutube headphone amplifier/NEX HR

I wouldn't describe myself as an audiophile but I do appreciate good sound and this amp sounds nice.
The different components are divided out sensibly within plastic bags and it's all packaged securely. The Union Jack origami was a nice touch :)
Putting it together is simple and it comes with the same PCB diagram and part list print out as you can see in the listing.
Microwavemont was helpful and quick to answer my questions.

Excellent product!

Dsp radio

For DSP radio version 3

Very nice radio, I use it for sw reception, and also for reception of the long wave. Here in europe we still have long wave radio emitters (french german and of course BBC ). It is difficult to find a good long wave receiver.
I am very surprised with the quality and the rapid sending.
Thanks very much

Amazingly fast shipping, double protected

For ESP32 Audio developing board (ESP32-ADB)

I received the package today after only 8 days. You should know that this never happens with Romanian postal service.
I was happy to find the board in a sealed water-tight anti-static bag, next to the color-printed instructions and a nice origami star, all put in 2 airbubble-padded envelopes, one inside the other.
I am out of nice words to describe how happy I am with this seller, the product and overall experience.

Thank you!

Neat kit

For DSP radio version 3

I bought this with nostalgia in mind, soldering a FM radio kit was my first electronic project many years ago, only it wasn't SMT.
I was delighted to discover an origami in the package, not only because I'm a fan of Japanese culture and Arts, but also because thinking objects have geographical origins is another way to travel the world without moving, and this one is a good reminder :-)

I still have to get a reflow station (thinking about this one https://www.tindie.com/products/LafrasH/modern-electronics-reflowr/ ) to get it assembled though.

Response from microwavemont | Sept. 6, 2017

Thank you for wonderful review including origami!! (actually it is my wife's made!) Just for small amount SMT soldering, indeed, we can do it by a fine soldering iron and magnifier (in my case, due to aging eyes..). For example, in the case of 0603 resistor( and capacitor), putting small amount of solder in one PCB land and re-melting it to fix resistor and the other can be soldered by soldering iron. You may need soldering wick to remove too much solder. Anyway thank you for reviewing and please enjoy Radio!!

The programmable logic counterpart to an 8-bit AVR dev board

For VHDL training board

I was looking for something analogous to 8-bit AVR microcontrollers, but for programmable logic. This CPLD board feels just right for me to get started.

I managed to follow the "How to" instructions and complete them in about an hour or two (not including Xilinx tools download and installation). Only minor detour was that the complete "how to" instructions was for the revision 1 (with a different CPLD) and the revision 2 instructions only tells what's different from revision 2. Of course I forgot to take the differences into account later when I followed the instructions... :-)

Over all, I'm pleased that I got from code to button+LEDs working in "real life" this easily and quickly. There aren't a lot of steps needed, and the "how to" covers the whole process, including installing the tools (and workarounds for Windows 10!). It did not assume any prior knowledge or installed tools, which was very helpful to me.

Next I will try to program the CPLD with code generated from MyHDL. It lets you develop and unit test the logic in Python and then extract Verilog or VHDL code from that. After that, maybe I'll try a faster crystal and experiment with, say, one of those cheap ultrasonic sensors. 8 Hz is very slow, but I realize that it is a quite good starting point. I did not have to implement a counter in code just to bring down state changes to human reaction times.

Also, the shipping was incredibly fast (less than a week from Japan to Sweden, and that included a week end).

Response from microwavemont | July 22, 2017

Thank you so much for nice review comment!! We need to take additional step (windows command line writing) which will not be required for expensive and established CPLD/FPGA board but I am also happy to read you have successfully written your own code on it. The on-board crystal is 32.768kHz and divided 4096 is just 8Hz and if some higher frequency is needed, please swap crystal to higher one (for example 8MHz or 16MHz) or taking another tap from 4040 12-bit counter chip. Thank you so much again!!

Wow

For Nutube amp kit, a vacuum tube in new century REV2

The kit is easy to assemble. Board quality is good and had no issues with solder pads or anything. The slowest part was carefully inserting all of the Nutube pins - takes a little patience. Fired up the unit and adjusted the left and right balance to center the sound.

I was blown away at how amazing the sound was! I typically use a decent usb DAC and this device was a totally different experience. I'm not an audiophile, but I can really appreciate this quality.

Response from microwavemont | July 21, 2017

Thank you so much for wonderful review on Nutube headphone amplifier. As you noticed, indeed, the sound from Nutube is clearly different from the one from solid-state semiconductor amplifier. Nutube is a kind of new invention, currently exclusively available from KORG/Noritake. Please enjoy wonderful sound. Thank you!

Michael | July 19, 2017

If you want a new age tube amp, this is the one for you.

For Nutube amp kit, a vacuum tube in new century REV2

Any audiophile will tell you that the best sound comes from audio piped through a vacuum tube. Something about the audio signal going through a vacuum triode slightly distorts the signal and gives it that legendary classic "warm" sound. The classic sound many recognize from old school vinyl records. The sound from old school AM radios. Many yearn for that sound. Alas in this day and age most audio amp systems use plain old transistors that simply amplify the signal straight up. No "warm" sound to be found.

Now for all the good the legendary vacuum triode has accomplished there are a few caveats. First off, they are typically rather huge. Second, many require very high voltages on the main supply to work correctly. Lastly, good luck finding affordable vacuum tubes that are designed properly.

So what's a person to do? Well, remember the old school vacuum displays on many devices from the 70s through early 80s? Those are VFD, Vacuum Fluorescent Display, devices. Those things are basically using the same glowing effect classic triodes use to make the symbols. VFD is basically a smaller and more advanced triode. Low power usage and much smaller.

A company figured out how to take this VFD tech and use it as a dedicated triode. Thus we now have the Nutube made by Korg. Old schoold triode in a new school VFD form. Low power usage and classic "warm" audio sound. You even get the classic vacuum tube glow from these things.

That is what this audio amp uses. New age VFD triode amp. Gives that legendary warm distortion effect naturally. If you want a decent amp that gives the warm vacuum sound but want a small and low power package system get this thing.

Assembly required. Get your soldering iron warmed up.

Response from microwavemont | July 21, 2017

I wish to express my deep gratitude for your great and detailed review on Nutube headphone amp. Indeed the review is better than my item introduction. Nutube is really a kind of new technology on vacuum tube. I've noticed some hardware hacker tried to make amplifier by pure VFD display (digit display) but this time KORG/Noritake specifically produced VFD for audio amplification. I hope you will enjoy wonderful sound produced by wonderful Nutube "tube". Thank you so much!
