Hi, I have a 1962 Amelco R-390A and a Collins R-390 for sale. Both can be seen at the Dayton Hamvention this week. I'm asking $600 for each. Both units are working radios and are in good shape. I also have a shock mount cabinet and a spare audio module and power supply with tubes for the 390-A.----I'm in spaces 941 and 942 at Dayton. 73, Ed, KØBKA
