Jewel 2

About the Jewel 2

The Omak Jewel 2 is a valve amplifier praised for its no-nonsense design, featuring low feedback, low distortion, and high current drivability. It uses output transformers rated at 600VA, which is substantial for a 50W amplifier, allowing it to handle complex speaker loads such as electrostatic speakers. The amplifier includes considerable capacitance in the power supplies and regulated supply voltages for the input and driver stages, contributing to its stable performance. It is capable of delivering around 38 watts per channel and can play very loud with clarity. The design emphasizes a complementary symmetrical class-AB amplifier topology with global feedback and an idle current between 50mA and 100mA. The supply voltage for the output stage can be switched to approximately double the value for high voltage demands, enhancing its dynamic capabilities. The amplifier is noted for its ability to drive difficult loads and maintain sound quality with low distortion and high current output.
