The so-called "Gainclone" is very popular in
the DIY-audio community; the simplicity, low cost and surprisingly
good results mean that you really ought to try one yourself :-)
These amplifier are on hold, but the research for this project has resulted in a number of other projects and articles on this site:
- Introduction to Gainclones - Read this if you've never heard of "Gainclones"...
- Gainclone experiments - The research carried out during the planning of this project.
- Micro-Amp - A miniature stereo amplifier using an LM4780 and delivering around 25-30 watts per channel. The enclosure is designed to compliment my Audax mini-monitors.
- A4 Power Amplifier - Uses four LM4780's to give 4 times 50 watts or 2 times 150 watts, built into a compact DIY aluminium case.
Project details
- Analogue stages - Details of the LM3875 implementation (one day!).
- Control circuits - How the amplifiers are controlled by the 12V trigger input and front panel switch.
- Construction - How these will be built into old power supply cases.
