DIY: 25dB attenuator V3->R09-HR
« on: February 25, 2010, 09:41:24 PM »

Many, many thanks to everyone who gave advice.  I have built a couple of attenuator barrels and tried them once with great results.  Here is how I did it (with much community help):

Have a suggestion?  Let me know and I will update the doc.

Now.... What would be interesting is a comp (with lots of low frequency) that compares the cable to the alternative.

Maybe?

source > v3 @ 40db > attenuator > r09

vs.

source > v3 @ 15db > r09

(the choice of 40 and 15 db was arbitrary)

Great stuff! Maybe drawing the schematic out and including it with the step-by-step sequence would help those that want to try this. I've made many similar cables over the years.
