Anthony,

I think Radio Shack still may carry them.  Last one I bought was a few years 
ago and was around 3 bucks.   It's  smaller than the first joint of your 
little finger and has 4 color coded wires coming off it.   If you don't have 
sighted help  or a color identifier to separate the  4 wires into the proper 
2 pairs,  a beeping  tester should do the trick.   The insulation on the 
wires is super tough and it's easy to  cut all the way through the  whole 
thing, so be careful.  Check Radio Shack for "audio transformer".

 They also carry something called  a "ground loop isolator"  for around 17 
bucks.       There should be info on the RS site.   I think this is more of 
a plug in type of thing, so  you may need adapters depending on what  you 
are connecting to what.



Happy humming,  Steve KW3A
