I bought this for me and my kids to experiment with together. I have three kids ages 10 -14 and they really enjoyed putting together this kit and soldering parts on. This was the first time my kids and I have done something like this. Colorful very easy to read, and understand instructions made this simple to learn and do.

This thing is awesome! Put it together in about 3 hours including testing each resistor. Worked right away. Tested it with my DDS signal generator. This thing is very accurate. It's not the same as my analog Tektronix scope but I don't have to count the gradients for frequency and voltage which makes it handy for quick measurements. It also doesn't go to 100Mhz but is plenty for tube and SS amp audio work which is what I do. Also can run on batteries so is great for being part of a mobile lab. What a fun gadget.

Still soldering it together (the well reviewed soldering iron I purchased turned out to be junk) but it was a very well put together kit! Easy instructions and all the parts were there as required.

This little kit was a lot of fun to build, and good practice for soldering tiny parts. Had to resolder one connection when it was finished to get it to work. It is a good idea to test all parts before putting together, but I found no problems with the parts! Color codes on the resistors are somewhat difficult to read because of size and washed out colors. Ohm-meter check the resistors for sure. Scope is low bandwidth, but useful for audio testing. I wish that a case was included, but I see several sources on-line.

Had a great time building and is very useful for a part-time electrical tinkerer.

Worked flawlessly for a day or two, then magically stopped working. Was fun putting it together, and viewing the different components. I am pretty sure a transistor blew during operation as I can feel a massive amount of heat coming from U5.

I can appreciate that this is a genuine kit from an authorized seller, but once I got the thing together and soldered up correctly, it doesn't work. D2 gets extremely hot with just the 9 volts after a few seconds. V+ gives me mV output. What did I expect for a 20$ kit though. Really doesn't surprise me. I took great care in measuring resistance and capacitance too. Can't test the inductors though, but they weren't short circuited at least. I've reflowed each and every point, even headers, and all I get is a burning hot diode. Thanks guys.
