Radio Shack sells a bag of colored plastic RCA's; unscrew the cover, bend over the metal to short the plug, apply small amount of solder, screw cap back, and fill void with silicone. 8 plugs for about 5 bucks. Any cheaper ya gotta steal em!! Oh yeah...INPUTS ONLY!!!!!
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?
