hi
thanks. yes its universal, so has a removable tip which can be fitted either one way or the other (negative or positive). so should i infer from centre positive that i should be setting it up in the positive alignment? the word 'centre' suggested to me that there was a third 'middle' option between positive and negative.. (im not very good with electronics in this way..!)
