RCA Caps

There is a small operation making and selling true RCA shorting plugs: Aurora Tronics in Sandy Hook, CT (phone number 203/426-9599). I bought some a couple of years ago, and they were cheap: $19.95 for 20 plugs. They also offer RCA phono cap covers (non-shorting, for outputs), at $7.95 for 20. They sent them to me with free shipping! Cardas’ protective caps look nice, but do nothing, claims for providing shielding against RF and EMI notwithstanding.

Appreciate that recommendation, but it appears to be a dead-end. The number is not valid, and the 860 version of CT area codes is a different organization. Googling for this outfit is also unsuccessful.

So, are there any other recommendations as to where to obtain caps and shorting plugs?

Search at eBay for "RCA shorting plugs" (without the quotes) and you'll find numerous sellers offering them, at low prices.

Like the Cardas Caps they don't having to be shorting type caps to be effective. Cardas type caps are simple covers for unused input and output plugs. They should be placed over ALL input and output plugs for max benefit. Copper foil can be used in lieu of the real McCoy. 

I found the Aurora Tronics plugs in a 2015 ebay ad. It doesn't matter who makes them, as long as the hot center pin and outer ground are soldered together, to create the short. Anything less is merely cosmetic.

Sorry if this was covered earlier but why not just use caps to cover the unused plugs? I bought a set of 5 pairs gold plated caps for around $15. These are just "caps" with no pin inside.
