FIRST you should look inside the case. If the RCA are soldered directly on a cicuit board is is MUCH harder to replace them. Better to check now, before buying the pile of female RCAs and THEN finding out you can't do it.
1) assume you have soldering expertise? 2) do you need PCB or chassis mounted connectors? 3) will you need replacement coaxial or straight wiring? 4) consider what wire and solder would you use exactly? 5) WBT's are a bit pricey for this application. Consider Cardas or Kimber connectors. Michael Percy Audio is another vendor possibility. Or perhaps have it done by a local tech at an audio shop.
