UPA-200/ RCA connection damage

[cheglie]

I realized my cable connection from my receiver to my amp was just a bit too short, tight and had bent/damaged my RCA connection on the back of the amp.  Just enough that it bends slightly in one direction.  Looks like it has a small crack at the base.  Can't notice in performance.  Still sounds the same.  However, I'm guessing if I need to detach and attach many more times it could break much worse.  Perhaps a replacement RCA part is available that I could install?   A little surprised it bent although a tight fit, it seems like it should be a little more durable.

Any suggestions?  Would rather DIY than send in to be repaired.

Sorry.  Realized this is wrong place to post.  Didn't see the UPA section
