Have you checked if you used all the correct materials? That you didn't substitute something because you guessed that it would work just as well? Did you read the steps to record something carefully and have executed them correctly?

Other than these general ideas I can't really know what might have gone wrong.

Hi snowlark, and welcome to TSG.

You will probably need some electronic test equipment to troubleshoot your problem. A multimeter that can measure very low voltage audio frequency signals would be a minimum and an oscilloscope might be preferred. The first step would be to see if the microphone signal is making it to the amplifier input. Then you make sure the amplifier has enough gain and power to drive the recording head with enough signal to make a suitable magnetic field.

What kind of wire are you using for your recording media?

Yes. The only substitution was the brand of amplifier (radio shack is no longer available)

Thank you! All great suggestions!!! We used a compass and multimeter to assure we had good connections and some transference of energy. We made a few ajustments and have managed a very poor quality recording. But it's still a recording and better than we were twelve hours ago. IncreasingIthe speed thetwire passes the recording head seems to have been key ! We are currently using vintage recording wire, figuring that was the best hope at achieving some level of recording. And being so fine and flexible was the easiest starting point. We will move to more typical wires tomorrow.
In terms of collecting some sort of data, is there a best option for taking a measurement for an audio recording?
