CGS Serge noise: Difference between revisions

'''CGS97''' the '''CGS Serge noise''' module can be built in several ways. In it's simplest form, it contains three basic outputs, White noise, Pink noise, and a random voltage suitable for use with Sample and Hold modules. An optional Sample and Hold circuit is included on the PCB. Alternatively, the basic version may be coupled with the CGS92 [[CGS Serge smooth and stepped generator|Serge Smooth and Stepped Generator]] to make the Random Voltage Generator module.

Note that the orientation for the transistors on the overlay is for vintage 2N4250 and 2N3565. The pinout of modern PNXXXX devices is usually the reverse of what was used with the 2NXXXX devices. In this case, BC557B and BC547 variant can be used as direct replacements for the vintage transistors, or PNXXXX devices can be used, but installed in reverse with respect to the transistor outlines shown on the PCB. Whatever your choice, the tiny transistor schematic symbol within the "D" is correct and can be followed.

== Notes ==

* 330R refers to 330 ohms. 100n = 0.1 uF.

* The module will work on +/-12 volts.
