Happy New Year!
If you want 10X it's actually 9M resistor and you could select a cap to stuff in parallel for best HF response on one particular scope or add the trim circuit which is probably a PIA for you, unless you have a fixed 10X donor probe, to take the BNC from.I guess this is the more reasonable one for audio use, instead of the trim cap you could select a fixed one for your scope.This is a nice one if you get a donor probe, one which has the trim on the BNC, not on the probe.This is in case you get serious into HF and you need to start from scratch.JS
Would it not be more simpler just to get a new scope probe that is x1/x10 switchable? Does everything for you.Mike
Usually fixed X10 probes are better than switchable, if you are working up to a few MHz it's fine and practical the switchable ones, of course.
For standard audio work, the switchable probes are just fine. Hell, they're fine with my 200 MHz analog bandwidth TDS2024. For high-frequency work, the 3" ground wire is more of a problem than the switchable attenuation. (The DPO3034 on my desk at work does not have switchable probes.)
