Here we have a pair of Electro-Harmonix 6L6EH Power Amplifier Replacement Valves/Tubes. They were taken from my Mesa Boogie after less than 4 hours use, as I replaced them with EL34s. Mint condition, perfect working order and plenty of miles left on the clock.
Electro-Harmonix is rocking the vacuum tube community with the superior quality of the "EH" series tubes. Electro-Harmonix sound effects are world renown for the soulful warmth of their analog sound. This line of "EH" premium tubes continues in this tradition of classic tone.
Modelled after the vintage RCA 6L6GC "black plate," the 6L6EH features large plate dimensions and improved grid structure for increased power handling capabilities. Also features mica spacers with metal springs to eliminate tube rattle and micro-phonics. The 6L6EH offers tone and performance superior to any other 6L6 or KT66 type.
