Are you using two Ground Masters when using the RouteMaster and 136/156? How do you connect all (136 or 156 / GM / RM) three?The best use of Puritan products is as a complete system; 136 or 156/GroundMaster or City/RouteMaster. I have done so with several stereos and a recording studio. IMHO, the RouteMaster is as important as the GroundMaster or City.
