My wife and I bought a very nice 1946 philco console off craigslist for $75. It works, but I can't get any stations, only static, which changes pitch and intensity as you go down the dial. Has a large built in antenna that is movable, and it hooks to terminals 1 and 2, and terminal 3 has nothing hooked to that one. How do I get this to tune some stations?
