Better I am not looking for the ones from the ads,Orion,PPI,Directed merger but the flat blue,grey,grey/black,green,green/black. I think the ones you saw are the latter of the two, if not tellme where to find them on ebay
Good luck, I've got a 2150am and I could see how they get lost. The plug doesn't fit tight like the ones in the Art series. I would always have a speaker cut out and it was that **** plug. Best of luck. (Needless to say that beat up old amp still sounds great)
