SV-EL34

The SV EL34 is a glass envelope power pentode intended for ultra linear audio frequency power amplification service in either pentode or triode connection and single or push-pull/parallel tube applications. The SV EL34 has an indirectly-heated oxide cathode, which may be DC operated for the absolute best hum/noise performance. The 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 amplifiers. The high sensitivity of a pair or quad of SV EL34's is an economical method to achieve high quality sound with a minimum of driving stage components
