Electro-Harmonix EL34 matched pair
The EL34 developed in the Physics Laboratory of Philips in Eindhoven (NatLab) and introduced in 1949 by Mullard manufactures with the aforementioned patented surpressor grid making it together with the other four electrodes namely the Cathode, the Anode, the Steering Grid, the Screen Grid. The so-called pentode tube arose, pentode derived from Ancient Greek Penta which means five.

Electro-Harmonix
Electro-Harmonix is a New York based company that has gained notoriety through guitar effect pedals. Started in 1968 by an audio technician and an ex-employee of IBM Mike Matthews, who is also a Rhytm & Blues pianist. In the nineties, Electro-Harmonix was taken over by the New Sensor company, which is also located in New York. New Sensor has its own tube plant in Saratov Russia where it has its tubes made under strict supervision from the EH USA. Now that Electro-Harmonix has 50 years of experience within the music world, we at TubeDirect are convinced we have chosen a reliable partner for the supply of new tubes.

Naast de Electro-Harmonix EL34 verkopen wij ook nog premium versies van de EL34 van Mullard en TAD

In addition to the Electro-Harmonix EL34, we also sell versions of the EL34 from Mullard and TAD

Matched tubes
 

This set of tubes is matched. This means that the measured values of the tubes fall within the same range and thus perform equally.
This is important for two reasons:
1. To obtain the same gain factor per tube.
2. For the same amount of quiescent current per tube.
The first requirement speaks for itself and the second requirement prevents the one tube where a higher quiescent current or bias is needed to make it work in the linear region will also be worn out earlier. Both new tubes and our NOS tubes can be ordered separately.
