As far as I know, I have the only Atlas 400 that left the factory in working order. It went to the hamfest at Oregon and was given away as a door prize then went to CA, from there to TX and then to me. The rig works excellent and I am proud to own it. There are 2 other owners that I know of, one in CA and the other in NC. My 400 is in excellent working condition and I find no faults at all. A fun little rig to operate. I also have the desktop power supply that came with it. I have all the Atlas models and other than the 400 , my favorite is the 350 with all options including delux power supply with clock.
