The "Beast" - A LM3875 Chip Amplifier

Bruce has put together a LM3875 based Non-Inverting Chip Amplifier using the LM3875 kits available from audiosector.com. He has affectionately named his project the "Beast". For the enclosure, Bruce used plastic and aluminum project boxes from Radio Shack. The power supply consists of a 200VA toroidal transformer and is housed in a separate enclosure.

Consistent with what most are chip amp kit builders have been finding out, Bruce has found out that these gainclone kits result in a great sounding amplifier at a reasonably low cost. For more information about this project, see The "Beast" - LM3875 Chip Amp.
