| The idea for this adapter was really born out of necessity. The 24.576-MHz crystal oscillator that is used in the Audio ADC 2000, (24 bit/96...
| This circuit (admittedly a big word for three connectors), was born out of necessity. Many years ago, when reliable scanners were still bein...
| There are many circuits for low voltage regulators. For higher voltages, such as supplies for valve circuits, the situation is different. Th...
| This power supply was designed for use with the ‘Simple hybrid amp’ published elsewhere in this issue. It is of course suitable for use in o...
| As opposed to the widespread Baxandall circuit (dating back to 1952!) a ‘paraphrase’ tone control supplies a straight frequency response as...
| Even the most experienced electronics engineer will undoubtedly come across these: short-circuits in places where they don’t belong. And the...
| The most dreadful electronics part is perhaps the toroidal core. Anyone who has wound one themselves can relate to that. Particularly if mor...
| A few months while scrutinising a great design for a pulse-width modulated audio amplifier with a 2x100 W power rating and a very small encl...
