[QUOTE="TaylorFade, post: 8103252, member: 618111"] Yep. I use the little DSO Nano v.1. I got it from eBay from a US seller for like $70 shipped or something. It's worth it's weight in gold to me. Not sure what you're talking about with the dummy load thing. I scope them unloaded first to get a reference voltage. Then I test them loaded down with subs. A "Dummy" load would be nice, but you're talking about several thousand watts worth of fixed resistors now. And that's some money. Fiixed resistance is the money when testing amp output. Because there's no rise and the voltage and amperage are in phase. You also aren't waking the dead or tearing up subs trying to set/scope/clamp the amp while it's playing full tilt. As for it's limits... mine has a 10x probe. The scope itself is only good for ~ 80vpp (volts peak to peak). That would only be good for amps up to about 3k or so. But there's a little "10x" switch on the probe that multiplies that voltage. I have no problem setting my 10k amp with it. Also... right this second... I am developing a product to set gains that allows you to HEAR the clipping/distortion. No scope, no DD-1, nothin. It's a pair of headphones that you put on, play a tone and adjust the gain.
