PenguinAmp Caffeine Ultra Amp

The "Caffeine Ultra" Amp is truely a high fidelity amp at the lowest price possible. It uses the amazing AD8397 opamp and two TLE2426 railsplitter to create the virtual ground. Furthermore, it includes two slide switches for gain and bass boost (8dB). Advanced customers agree: If this amp would be housed in a "commercial" enclosure the price could be raised up to $200!
