You Can DIY! Meet the Pentriode

This DIY-focused article introduces the Pentriode, a concept to explore the familiar idea of connecting commonly available pentode tubes as triodes, creating a circuit that excels in linearity. The Pentriode is formed by making one simple change to connect the screen grid to the cathode of a cathode follower. The article proposes different possible approaches, including for a mu stage, a design that the author previously wrote about for audioXpress. This article was originally published in audioXpress, May 2022.

QSC Confirms Split Q-SYS and QSC Pro Audio Operations

Anyone that attended InfoComm 2022 could notice that something was changing when, in place of QSC, the booth was taken by a company called Q-SYS. Small signs in that booth still showed the QSC logo and the slogan "This Is Q-SYS". Now QSC announced the appointment of the new QSC Pro Audio division with the appointment of a new leadership team of "veteran staff." QSC/Q-SYS remains a single company for now, and still shares the same board, with Joe Pham, as Chairman and CEO, and Jatan Shah as President, and Chief Operating Officer.
