A Three-Channel Tube-Based Guitar Preamplifier

Peter Delos details how to add tone controls to a three-channel tube-based guitar preamplifier. The circuit is a versatile building block anyone can use for his or her own preamplifier applications. The project is implemented with three 12AX7 gain stages. The tone control at the final output is a standard bass, mid, treble control circuit found in many guitar amplifiers. This article was originally published in audioxpress, October 2014

Preamp Muting Circuit

Preamp Muting Circuit

Oftentimes a muting circuit for the output of a preamp is left out of DIY applications as an unnecessary or annoying part of the project. This is usually due to the lack of awareness that a simple circuit can perform such a duty. Anyone who occasionally forgets to turn the power amp on last, or switch it off first, endures the annoying thumps and noises that often occur from the preamp upon power cycling. This article proposes a simple circuit for preamp muting. The article was originally published in audioXpress, March 2010.

T-reg: A High-Voltage Regulator for Tube Amps

Tube amplifiers can benefit from regulated and stabilized power supplies, especially sensitive preamplifier stages, but also (single-ended) power amps. But traditional high-voltage regulators add several extra tubes, complexity, and power losses, while good performance is not easy to obtain. This article, published in audioXpress, April 2009, describes a novel design that is very simple yet offers excellent performance. Output voltage is fully adjustable with a single resistor without any compromises in performance.
