iPod Super Dock Project (Part2) - This one goes out to everyone that has an iPod
or two laying about and an itchy soldering iron and thinks that the standard USB or
Firewire dock just isn't quite good enough. The tiny thirty pin dock connector on the
bottom of later model iPods contains quite a ....(circuit added 07/07/07) |

Isolated Telephone Interface - This circuit allows you to record audio from a
telephone line into a tape recorder or computer soundcard. Most of the parts for this
circuit can be scrounged from an old modem, with some work, it is possible to rewire
the modem circuitry and use the old modem case....(electronic design added 6/07) |

JFET992/3 Summing Amplifier Circuit - Summing buss and amplifier circuit for an
Audio Console design (circuit design added 08/08/08) |

JFET-MOSFET Headphone Driver - This amplifier is based on the MOSFET headphone
driver by Greg Szekeres. It has a JFET impedance buffer front-end and a choke-input
power supply. The sound characteristic of the amplifier can be tuned by adjusting the
low pass filter formed with the input capacitance of the MOSFET. Designed by

JLH Class-A amplifier - The 1996 version using the specified transistors with
+/-22V supply rails and a quiescent current of 2A has an approximate rms power output,
into a resistive load, of 10W into 16ohm, 20W into 8ohm, 15W into 4ohm and 10W into
2ohm. For minimum distortion, ....(circuit design 08/08/08) |

JLH Class-A Update - Tim is a professional musician (a classical concert pianist)
and so I trust his subjective judgement when it comes to assessing the accuracy and
realism of sound reproduction. Before Tim first contacted me, he had built a kit
version of the 1996 design, which he had ....(circuit added 08/08/08) |
