Heathkit clock speaker?

In article , ian field wrote: A good clue as to whether its a piezo sounder is that some other component would provide a DC path for the collector of the driver transistor - maybe an inductor or just a resistor if its a real cheapie. Isn't it easier just to look at it? A piezo sounder looks nothing like a moving coil speaker. The manual is available here, http://www.pestingers.net/Heathkit_m...sequential.htm I assume the OP has it but for others trying to help in the manual the speaker looks like a normal moving coil speaker |
