Replaced the cap just like @EvilWish stated, (I did quite a poor job at soldering as you can see in the picture)
But the clicking/beating is gone! It works perfectly and sounds beautifully!
Great post, has been very helpful, I used the same snip and re-solder method rather than trying to de-solder (tried at first but the tip of my soldering iron seems deteriorated to do this)
Thanks for all the help everyone!
