Yash redux
About the Yash redux PCB
Yash redux is an open source PCB design by scottericpetersen, published on GitHub under the GPL-3.0 license. It is a board, with 39 components from 22 distinct parts.
Other key parts include the LF398_DIP8, TL082 and 4093. By type, the board carries 18 resistors, 9 capacitors, 5 ICs, 4 transistors and 2 diodes.
From the project
An extension of the classic YASH sample and hold circuit
This redux adds (1) a white noise circuit (by Ray Wilson), (2) scaling of the YASH output to work with CV in (for example, for the Koma Elektronik Field Kit), and (3) a test oscillator for testing/tuning the rest of the circuit.
Note: R16 in the schematic is drawn as 1 resistor (7.9k). This is actually two resistors: R16a 5.7k + R16b 2.2k = 7.9k combined.
