Oooh, can you guys take a peek and if you do hae the HV option, can you take a few photos of both sides of the PCB and wiring?
And, yep, I'm already feeling a bit wary of that HV output hitting my scope.
I do have a Tek TDS210 and the inputs on that are good for 300v, but I can't say the same for my frequency counters, or the circuits I end up hooking it up to.
