The Morgan Jones Mini Tube Headphone Amplifier - This reverse-engineered version
of the famous EarMax headphone amplifier has just 3 tubes, uses no global feedback,
and is powered from an 19VAC wall-wart. Includes two additional versions of this
amplifier optimized for driving low impedance headphones and simulation files for use
with OrCAD Lite software. Designed by Chu Moy (circuit design added 01/08) |

The SESS Tube Headphone Amplifier - The author describes the construction of a
very simple single-ended, single-stage, single-tube (SESS) tube headphone amplifier
with a reference power supply that uses a tube rectifier in a hybrid Graetz bridge
configuration. Designed by Andrea Ciuffoli (circuit design added 01/08) |

The Technology of the Fuzz Face - The Fuzz Face remains an enigma today, perhaps
three decades after it first hit the market. This simple, two transistor circuit
remains for many the very definition of the guitar effects stomp pedal. What makes
such a simple circuit the stuff of legend?....(circuit design added 04/05/06) |

The Zen Headphone Amplifier - A single-ended, class A MOSFET headphone amplifier
with an active current source that results in increased efficiency (50%) and lower
distortion. The active current source is based on a patented design featured in the
Aleph power amplifiers from Pass Laboratories. Designed by Marcello Pellerano

Tone Control (Andy Collinson) - Based on the classic Baxendall tone control
circuit, this provides a maximum cut and boost of around 10dB at 10K and 50Hz. As the
controls are passive, the last transistor provides a slight boost. The output….(added

Top-Level OTL Tube Headphone Amplifier - This article shows my tube headphone
amplifier designs for driving headphones with an impedance of 200 to 600 ohms (I am
using these amplifiers with the Sennheiser 580, which has a 300-ohm impedance). The
problem with many tube headphone amplifiers ....(circuit design added 07/06) |

Transistor Organ (Aaron Cake) - This simple circuit can provide hours of enjoyment
as you learn tunes, play duets or just make some really weird sounds by pushing all
the buttons at once. You have probably seen this circuit before, it is fairly common.

while Samsung aluminum electrolytic capacitors are used to filter the solid-state
power supply. ….(design added 11/08) |
