nanoo and PS

With only the desire to build something small, being motivated by the Patek, the nanoo was designed. It is based on the LM3875 amp-on-a-chip (chip amp). See the other nanoo blogs for a full description of the amp. I generally use heavy glass plate on thick silicon feet to isolate all my equipment or thick Italian marble. These isolation plates will appear in future blogs so call back. I have changed the solid brass feet seen here to one at the front two at the back. Also I have removed the adjustable part, lowering the amp by a center meter or two.

The idea is the PS can be hidden and the amp only is visible. Possible good if you are space challenged e.g. a flat dweller. The nanoo has the ability to deliver over 100W RMS so small it maybe be put weak it isn't. Most of the cooling is through the case which measures 119 X 94 X 34 mm. From this image you can see the working end. Everything just fits at the rear and the inputs are at the front to keep the output and the input well seperate. Twin attenuators allow volume control and reduces Xtalk. The case is alive. By this I mean the paint is like a thick powder which never curs. Small and powerful and with a great sound-who could want more?
