- these gaps reduce heat conduction during soldering ground plane on only one tl074 and support Kassutronic's KS-20 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an arduino nano (other options probably fine), two 74HC595 shift registers (accidentally a pile in my collection) and the following procedure for assembly. As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that.
