Hi Nick!
Here are the results of 55 hours of the H8000fw functionning alone in the loop of the Rivera TBR-1:
6 "clics-clics" at random, thus a mean of one double click / 9H ; it is little !
They do not pass in the big verbs, cause I made the modification you asked (verbs in the machine B).
As results,the noise is rather unobstrusive ; I can live with ..
Yesterday , I had the last double click just after I puted en route the equipment for a concert :you could hear it in the HP ,but it was admissible..
cheers
