This is my first attempt at building a "proper" amplifier for general use, as opposed to the Mixer-Amplifier I had made earlier. This amp was made without too much concern to cost, hence several of the approaches I've taken may be sub-optimal from the cost perspective.
Overview
- Microcontroller-controlled preamplifier, with infrared remote control capability. Volume and other settings stored in battery-backed RAM.
- LCD Display for volume, etc.
- Three general-purpose line-level inputs, one tape input, one tape output.
- 70W MOSFET-based stereo power amplifier.
- Headphone output.
- +/-38V at 4A and +/-5V at 500mA power supplies.
