Electro-Harmonix EL34 Power Tube
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."

Electro-Harmonix 6550 Power Tube
The 6550EH is the finest current production tube for any amp using 6550 or KT88. The 6550EH offers the maximum power of any 6550 with the
linearity guitar and bass players want. With 42 watts of plate dissipation in tetrode operation and 44 watts in triode, the 6550EH
offers an improvement in power over even the most desirable vintage types including the Tung-Sol 6550 and Genelex KT88. This extra headroom
in a 6550EH equipped amp means bass players can finally realize the full dynamic range of the instrument and the sweetest tone available.
The extra ruggedness of the 6550EH was engineered with the punishing abuse of guitar amps in mind. The nickel steel side rod mica supports
ensure that the 6550EH will hold up in even the most punishing environment of high powered bass amps like the Ampeg SVT and combos
where the tube is only inches from the speaker and still deliver the sweetest tone of any 6550 or KT88. The 6550EH will greatly improve the
performance of any amp using 6550’s but can also replace the KT88 in any application. Item # 6550EH.
