I think Andy Moorer is Right ,Has anyone seen one of these units OR are they still on the secret list Hi ,On cost reduction ,the 390a is a simpler RX  but the 390 was designed in 1948  and by the early 50 s there were improvements in Tubes ie 6DC6 and mechanical filters and the same performance or better was available at reduced cost with less stages and no series regulators and much less power into the bargain ,I have both rxs in my possession and I can say that if you are listening to sideband on 40 meters in amongst the broadcast stations  there is NO substitute for the 2KHZ filter in the 390A , I have Watkins Johnson harris racal ect nothing comes close , also it is so easy to use with a TX having its own Ariel change over and muting circuit , sorry Guys but when it comes to the 390A ,I run out of Superlatives Hi
