Electro-Harmonix KT88
In 1957 Marconi-Osram introduced Valve Co. (GENALEX) KT88 in response to the high power tube 6550 (Tung-Sol 1955) developed in the US. These tubes became the soul of classics like the Dynaco Mark III, the McIntosh MC275 and the Marshall Major. Unfortunately, the production of this tube was stopped in the 1980s. Electro-Harmonix now makes this classic in an affordable version.

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.

Besides the Electro-Harmonix KT88 we also sell the premium KT88 from Genalex Gold Lion.

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.
