Electro-Harmonix EL34EH platinum matched pair.
The platinum matching process consists of a 24 hour tube burn-in period followed by a bias (plate) current measurement in milliamps.
The new Electro-Harmonix EL34EH is extremely musical and predictable with a sound that is rich, smooth, and highly detailed without being edgy. It is the perfect EL34 for vintage equipment and a sure way to improve the performance of modern equipment.
According to the technical journal, Vacuum Tube Valley, the ...new EL34[EH] comes very close to the sonics of a Mullard EL34... They go on to say, ...The Electro-Harmonix tube is balanced throughout the entire music spectrum. Bass goes deep and is tight, mids are sweet and well defined and highs are detailed and extended.
