Broken banana plug and stuck in amplifier


Hi, seek your advise how to remove the broken banana plug which is half-broken when i pulled out the plug, it's rather hard to clamp as it leaves a little metal.

The binding post of amplifier (E280) is unable to unscrew fully and to be removed,  

Appreciate if you have similar experience and how to remove the remaining banana plug out from amplifier .

I have a couple of different sets of dental tools that I use for such things. Several of the tools have different size and angled points to get into small spots. You can get a cheap set at Harbor freight to start with.

All the best.

Any chance you can insert a drill bit that is smaller than the piece you are trying to remove? Wedge it in there and spray a small amount of WD40 to reduce any friction, then using pliers turn the bit to a point of engaging the banana piece the pull on the drill bit. If any movement is witnessed then repeat the process except the WD40 and it should work out a little at a time. 
if you use the rat tail file make sure to insert the tang in as the file is designed to cut on the push stroke and won’t engage the broken piece as you pull.

good luck

There are small special wire locksmith use to pull out broken keys in locks. Can probably find them on Amazon. They have one way teeth to grab the stick piece. 

That just happen to me! I used a drill ( very carefully)with the correct size drill bit and Bob your uncle

Many thanks for all your suggestions and safety precaution.

I managed to use tweezer to slowly and hold tight on the tip of tweezer to pull out gently without damaging the terminal (the broken banana plug tip was split in loose, so use tweezer to grab the short piece and pull.  (The tweezer is with anti-static tip, used to pick screw from PCBs) 

From the bad experience of banana plugs, I would use spades type speaker cable instead next time.
