Yes, super. Just grab a few 10 watt non-inductive resistors. Perhaps a few 5, 10, 20 and 30 ohm parts. That way you can combine them in different configurations to form any value you need. Then also grab a few 250V polypropylene film, metal foil capacitors in 0.47uF and 1.0uF values. This will get you where you want to be.I've included a link to a previous forum post that contains a chart of resistors and the attenuation you can expect from them. The post is called "Compensation circuits"
