Re: CDV-700 Operation Question

I forgot to mention that the test with the Ludlum/Vic 6A was with a LND 7311 pancake and the Ludlum was adjusted to have the same voltage as the Victoreen.

Re: Smallest piezo speaker?

If it was piezo element, it would be OL regardless of orientation.The fact that the pins are marked with a polarity indicates that is not a simple piezo

Re: Smallest piezo speaker?

Here is my smallest. I got it from Radio Shack when they were closing stores. Most of the ones I got were larger. Size matters. This doesn't make much noise.
