Sure, it's quenching somewhere, but where? 1st notch? 4th notch? I want to see for myself. It's not an urgent matter. I'm just curious.
Also, good sparks don't automatically imply good quenching. While analyzing his single static sucker gap, Gary Lau discovered that even with crappy quenching, a Tesla coil can produce satisfactory streamers. Hey Gary, how did you scope that without killing your scope?

Yeah, I've thought of that. My scope is a Japanese relic from the late 70's. I gave $45 for it. If it croaks, I'll get over it.
What about optical probing? Could I rig up a photo diode coupled to the input channel on my scope and let it "watch" the spark gap? Does the spark gap arc accurately reflect spark gap performance?
