LM4780 Micro-Amp:

My new computer needed a compact amplifier to drive the PC loudspeakers. After some thought, I came up with a design to compliment my Audax mini-monitors using the LM4780.

This "stacked" view shows how they are almost the same size as a CD.	This rear view shows how the amplifier connections are hidden.	A closer look at the rear panel connectors and the custom power cable.
