tubbytwo Posted November 28, 2004 Report Share Posted November 28, 2004 I have a one tube AM transmitter that I plug a portable CD player in to so I can broadcast old music to my antique radios. I would like to have a neon bulb on the front of the transmitter to monitor, or flash bright/dim with the music. Right now the only way I can tell if it's working is to turn on a nearby radio. I have a pilot light for the unit but this only tells when it's on. It can be powered by AC and triggered by the output (line out) of the CD. Any help here?

ante Posted November 28, 2004 Report Share Posted November 28, 2004 Tubby,What kind of AM transmitter do you use? Is it a tube circuit them maybe you can tap voltage via a transformer from the anode side to a neon bulb. Quote Link to comment Share on other sites More sharing options...

Lou Posted November 30, 2004 Report Share Posted November 30, 2004 HiYou can try connecting one side of your NE-2 to ground via a 100pF capacitor and use the other end to probe various points of the transmitter (maybe the antenna) until you find the right spot.Lou Quote Link to comment Share on other sites More sharing options...
