Circuit Board Layouts - By Pete Zenner - DAA Audio Amplifier Spy Circuit
Sioux Falls, SD.
It is rare indeed for anyone to give up their board designs on a professional Electronic Surveillance Device
- In the case of my DAA Audio Amplifier - Long Range Spy Circuit,
Zenner did. It required a lot of work, hours on end - and re-work to
build the device - from a schematic to a board design and prototype and
yet, more board designs, and other prototypes to a functional device
with a working board. That is the mark of a true pro.
