    Selling my GW 622G 20MHZ dual channel scope that I used for my own personal vehicle. Everything works perfectly and it has nice features that help you get the maximum clean output from your amps. It is in prestine condition as well (See pics below)

    Comes with AC Power Cord and a BNC Adapter that lets you hook up speaker wires.

    Price lowered to $150 SHIPPED! I will also throw in free insurance This unit sells for over $400 new.

    Payment via Paypal. I only ship to a confirmed name and address on Paypal.

    The waveform below is from bench testing an MB Quart amp. Note that its extremely hard to capture the fast moving waveform on Camera so thats why it looking a little fuzzy.
