I saw that too John, and figured the same.   Thanks for confirming.   
I've had less than stellar luck with this multicoupler, mostly 
heat-related, but the addition of a muffin fan seems to have helped.     
The PCBs aren't too robust to begin with and repeated repairs haven't 
helped, I may lay out a board so I can replace them with new ones as 
needed.    Good performance as you'd expect.
