New Version of Control Board for AAA-1

Hello all,
There is a new version of Control Board v.1.10. Now it has two different limiters which limit the output voltage either 4 V pp or 2 V pp in order to protect the receiver front end. Read Some minor changes are made also in the amplifier PC board to ease the production.
All models of AAA-1 kit are compatible to each other and can be interchanged. The control signals in all models do not differ between each other and they can be used in phased arrays with VDL-1 variable delay line. There is no change in main electrical parameters as gain, frequency response, noise and dynamic range compared to previous model.
