You Can DIY! A High-Voltage Delay for Tube Amplifiers - The Sequel

In this project for audioXpress magazine, Jan Didden offers a modern update on his original 2014 high-voltage delay design, which he built to complement tube amplifiers. The new unit needs no additional outside power, and allows setting the delay between 20 seconds and 254 seconds, which should cover all requirements. The article describes the complete project, and there's a DIY kit available at diyaudio.com. This article was originally published in audioXpress, November 2019.

A Modular Hybrid Amp System

Tubes or transistors? Whatever your prejudices, this article may make you change your mind about how you view hybrid designs. audioXpress featured this modular hybrid amplifier project in February 2001, which was referenced multiple times by other authors in many subsequent projects. The project features a shunted regulated push-pull (SRPP) stage design, using the ECC82/12AU7 tube combination, followed by a power stage, using two to eight complementary power MOSFETs in parallel.
