AMPEREX TUBE TYPE 6CA7 / EL34

   The 6CA7 is a power pentode designed especially for high fidelity audio systems.  It has a plate dissipation of 25 watts and delivers high power without drawing control-grid current.

   The 6CA7 features high efficiency with extremely low distortion.  Great care is taken in manufacturing so that there is very little spread in characteristics of individual tubes.  Thus, the rated output power can be obtained with all tubes.  The tube also features high sensitivity which results in low distortion introduced by driver stages.

   The tube features a large plate dissipation reserve.   The high allowable grid leak resistance improves the performance of preceding stages.
