Electro-Harmonix Factory Platinum Matched QUAD (FOUR) EL34 EL34EH Power Tubes
Matched QUAD Electro-Harmonix EL34
New, factory platinum matched set of four Electro Harmonix EL34 tubes.
These are burned in for 24 hours, factory matched at real world voltages and then the test results are labelled on each tube box.
This new production EH tube is manufactured at their Xpo-Pul factory (also known as Reflektor) in Saratov, Russia.
The Electro-Harmonix EL34EH tube is extremely musical, 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 tube 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.”
The factory matches these at 400V plate, 250V screen and -17.52 bias. Insist on factory platinum matched tubes for best performance.
They are all recent date codes.
