AMPEREX TUBE TYPE 6CA7 / EL34The 6CA7 is a power pentode designed especially for highfidelity audio systems. It has a plate dissipation of 25 watts and delivers highpower without drawing control-grid current. The 6CA7 features high efficiency with extremely lowdistortion. Great care is taken in manufacturing so that there is very little spreadin characteristics of individual tubes. Thus, the rated output power can be obtainedwith all tubes. The tube also features high sensitivity which results in lowdistortion introduced by driver stages. The tube features a large plate dissipation reserve. The high allowable grid leak resistance improves the performance of preceding stages.
