TAD EL84-STR matched pair
The EL84 developed in the Philips Physics Laboratory in Eindhoven (NatLab) and introduced in 1953 in Mullard radios. The EL84 was introduced as a cost effective alternative to the EL34 especially when it was used in so-called 'Table-top' radios where driver tubes could be omitted in these designs due to the easy control of the EL84. Now the EL84 is used in old VOX, Fender, Mesa Boogie guitar amplifiers and as a new application in headphone amplifiers.

TAD
The Tube Amp Doctor, or TAD for short, in Germany, selects and tests vacuum tubes since 1993.
Founded by Andreas Hecke, TAD offers individually tested and, if desired, matched and/or balanced tubes at an attractive price.

In addition to the TAD EL84, we also sell a premium version from Genalex the N709 and EL84’s from Mullard, Tung-Sol and Electro Harmonix.

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.
