Improved JJ EL34, with a modified cathode.
Hint: if you replace an EL34 with an E34L you should also check the bias.
The price applies to one tube.
To get matched tubes you must order the number of tubes that you need and select the needed matching-option. For example: to get two quartet you must order 8 tubes and select the "quartet" matching. If you need a pair then order two tubes and choose the "pair" selection.
