Joe,
Enjoy the Doubler! I enjoyed play-testing it
I had a collection of 25 or so amateur radios from the 40s and 50s--Hammarlund, Hallicrafters, National, Johnson, etc...still have a couple in addition to my more recent issue ham gear--mostly Kenwood. Love those old Philcos, RCAs, Crosleys, etc. I also have a Bakelite or two from the 50s--loved those Bakelite cabinets!! Still have a huge box full of tubes & other parts as well.
Jim
