Hey Squirrel guy ,

Just for future reference , all those Zenith "propeller dial" mid 1950s AM FM 7 tube radios used a neon pilot light and they made no noise on AM . The example I have is a "T-825" which of course is 8 tubes , it's basically the same as the 7 tube but with a 6AB4 as a separate local oscillator . I'll enclose a couple of "action shots" of the neon in operation .
