Short Out Plugs


I stumbled on this concept in one of my pre-amp manuals. The factory recommends I use SHORT OUT PLUGS in all my unused inputs. I've seen them for sale but $6.00 per pair seems a little steep. Can I make them myself? If so how?

Thanks guys. Dare I ask if these plugs would be useful in other parts of my system. Unused amp or dac inputs? Please let me know. I only want to make one trip to RADIO SHACK. Again many thanks for the money saving suggestion.

Sean, is there anyway to make a shield plug?
Thanks Sean. I'll take a look at the silicone I just bought. I may omit this step completely. Sws2 I don't know yet but I am going to find out. The engineer's at Theta thought enough of this procedure to mention it in the manual. Could someone tell me if it is safe to use these plugs on an amp or a dac before I try it? I do enough smoke testing at work. I'd like to avoid it at home if possible:~)
Since you asked here is a quote from my Theta Casa Nova
manual. " The Casa Nova can be susceptible to excessive RF. Shorting plugs in all unused inputs will improve the sound quality and may reduce the susceptibility to RF induced anomalies".
One quick continuity test and mission accomplished. Thanks everyone for the good advise on this thread. I built 12 short out plugs for under $12.00. I think I'll do my other pre-amp just for the Halibut. You know I even think I noticed a difference. That is my cheapest tweak to date. Thanks again.
