As the old man speaks again, back in my Dynatrol days (most with all the same factors) most engines were recommended to use a 2.5 amp receiver!? I think they sold 4 ratings.? My AM PA pair used a tethered 6 amp unit. The main problem was with the OMI S series switchers--so little room, plus those guys sometimes required heat sinks.? The owner would almost yell at you returned a dead unit, and the unit was overcooked!?

When i sold out of that system I was surprised that a 1.5 amp DH seemed to be okay.? With that being said, we all seemed to want more from smaller packages.? There are some studies from the people who make the circuit boards regarding their life spans and initial factory failures.? Would be nice in helping picking them ==--like consumer reports for us!? Maybe that's something for AI!
