I have a pair of ar3a's that I purchased from a buddy back in the 70's. Recently, AudioLab of GA (Doraville) inspected them and advised all 4 pots need to be rebuilt or replaced. All speakers were tested and all are working. They reglued a loose coil on the crossover and a dustcap on a woofer. They told me the repair for the pots would be $300. In any event, my wife has had some huge medical expenses lately and I need to sell these units. If interested please let me know. My e mail address is dion1564@aol.com. They would be available for pickup at my office in Peachtree City GA or you could pre-pay the shipping costs. You will have to let me know what you are willing to pay for them. I have no idea. Thanks & regards, Joseph Dion
