EL34/6CA7

Hig h P e rfo rm a n c e Au d io P o w e r

P e n t o d e

he Svetlana^™EL34 is a glass envelope power pentode having a plate dissipation rating

of 25 Watts with convection cooling. It is intended for audio frequency power

amplification service in either pentode, ultralinear or triode connection and single or

push-pull/parallel applications. The Svetlana EL34 has an indirectly-heated oxide cathode,

which may be DC operated for the absolute best hum/noise performance.

The Svetlana EL34 plate is made from a laminated material that improves heat transfer and

has superior performance under overload conditions which are often seen with guitar amplifi-

ers. Close manufacturing specification tolerances and improved processing provide enhanced

reliability and superior sonic performance. The high sensitivity of a pair or quad of Svetlana

EL34's is an economical method to achieve high quality sound with a minimum of driving

stage components.

The Svetlana EL34 is manufactured with the original Mullard design in the Svetlana factory

in St. Petersburg, Russia, and is designed to be a direct replacement for any EL34/6CA7 or

equivalent. The Svetlana EL34 gives electrical and audio performance very similar to that of

the original Mullard EL34.
