    I find out that R1 should be replace with R2. pvever i had the same problem as you. Now with this change both signals are correct.
    The adjustment doesn't work very well but for me it is ok.

    Correct: R1 520K/ R2 5.1M

    Sorry for my bad english
    Thanks SarverSystems for the upload.

    Should I update the list? Or is this resister swap used just to fix it if the waveform is not correct?

    Anyone else buy one of these oscilloscope kits? Is there a "recommended" power adapter (wall wart) to go with this kit? The auctions just say use 9v adapter but fails to list connector size to fit the oscilloscope's power jack.

    Did anyone ever receive any assembly instructions?

    These small scope are very attractive, because of their price and their size. The problem is that it is totally unsuited to troubleshooting pinball machines.

    Since the late 70's, the pinball machines are built with CPU-based electronic boards. Which usually work with clocks of more than 1 Mhz. The bandwidth of this kind of scope does not exceed 200 Khz ... With that, you can not even control if the clock of your CPU works properly !!!

    It's just good for measuring audio signals, but certainly not for testing CPU boards.

    The model DSO068 is a better choice. It's a scope and a frequency counter. It's got a 3 Mhz bandwidth for the scope and can measure up to 5 Mhz for the frequency counter. Plus you can run it from either a USB connection or a built in Li-Ion (not included) battery. It includes a real oscilloscope probe instead of some cheesy alligator clip cable.

    The DSO068 is only a few dollars more in price than the DSO328 scope.

    Any updates on this topic? Anyone else bought/built these kits?

    ya know -- for fifty bucks, it's tempting to just get one for the heck of it.
    Pretty low bandwidth but at least it can pick out fundamentals of a pinball machine's typical clock & control signals.

    Currently I just use my antique Tektronix 1631D for about everything when testing this old slow stuff. Logic analyzer with built in O'scope (50MHz). Huge, heavy boat anchor but still works well. Just to have a small scope that weighs less than a trillion pounds might be worth it.

    Quoted from G-P-E:

    It's sad when the wall wart to power one of these low cost digital scopes is almost bigger and heavier than the scope itself.
