Any old AM tube radio fans out there? I have five or six old wood cabinet Zeniths from the 30's and 40's. The AM offerings are getting thin these days so I decided to try one of these: http://www.sstran.com/ Now I can play anything I like through them. Pretty neat. Hook it up to whatever source you like (RCA input) and it broadcasts an AM signal up to 1/4 mile that you can pick up on your AM dial. The signal is clear with no drift. They will sell you one pre-assembled if you are not into the electronics soldering thing for an extra $50. Small family owned business. I am not affiliated but just a happy customer. Gave my old clunkers a new lease on life.
