Ruby Tubes 12AT7CZ (aka ECC81) Selected Preamp Tube is a high grade, moderate gain tube.
The 12AT7CZ (ECC81) tube is a low noise and low microphonic preamp tube. A good choice for phase inverters and reverb circuits calling for 12AT7 tubes.
The JJ ECC81 tube also refereed to as a 12AT7, is known for its warm and smooth sound, making it a popular choice among musicians and audiophiles. It was widely used in vintage audio equipment and can still be found in some modern audio products, especially those designed to recreate classic tube-driven tones.
The 12AT7CZ (ECC81) tube type is equivalent to the North American 12AT7 tube and can be used in any 12AT7 or ECC81 circuit.
