This document is an application note of the Printed Circuit Board (PCB) layout techniques in operational amplifier precision design. It discusses the PCB effects experienced in high DC precision op ...

Traditionally, tube power amps were all point-to-point (PTP) wired or of stripboard construction. Components were wired to a long tag board, which was then mounted under a metal chassis. From the tag ...

[Simon] wrote in to tell us about a headphone tube amp that he just built. It is based on schematics at diyaudioprojects.com that were actually featured on Hackaday in the past. [Simon’s] design adds ...
