Psvane new  EL34 vacuum tube new
Product name:Psvane new EL34 vacuum tube new
Item:GZ-EL34
Price:$22.46
Details:

L34

High capability audio frequency output pentode tube's anticathode limit dissipation power is 25W. In audio frequency amplifier, if single tube is used to amplify A1, the output power will larger than 10W; if two tubes are used to amplify AB1, the output power will larger than 35W.

EL34 is the same with 6CA7, and can be exchanged each other.
