      I am looking for a Stall buzzer that doesn’t need the control box. Mine had a long delay and was told to cut out control box and hard wire buzzer. That doesn’t work. Now I’m stuck. I need a buzzer that will work that doesn’t need the control/driver box.

      The delay unit is a separate module from the horn. The delay module was added to the AA-1 in the 1971 timeframe, the early ones did not have it.
      I think any 12V Safe Flight buzzer should work. You might check with Fletchair or Yankee Aviation to see if they have any working buzzers.
      The delay units have been dying and hard to find replacements. The one in my ’76 AA-1B is still working.
      See attached drawing. #14 is the delay controller, #19 is the horn.
