I ALWAYS try to steer people away from tubes such as this. I am speaking on Electro-Harmonix, Groove Tubes, Gold Aero, etc. The reason is that they are simply rebadged tubes from the companies who make them(Sovtek, Svetlana, JJ, Ei, Shuguang). They take those tubes, culled from NORMAL production lots, put them through a more QC, and mark the price WAAAAYYYYYYYYYYY up. Unnecessary and an ill advised purchase. You may get a prettier or more colorful graphic on the tube, or some QC test info(even written on the tube), but they can NEVER be any better than the lot they come from. I am not sure whose 6L6 they are using(only saw their 6L6 ad once), but they very well may be from Sovtek or Svetlana. I personally normally prefer output tubes from Svetlana over Sovtek. On top of that I prefer output tubes from the former Czechoslovakia(JJ, formerly Tesla and Teslovak) over Russian tubes. For EL34, I only recommend two tubes. Svetlana EL34 if you want a mellow sound(closest to the old Mullard), and JJ E34L as the best everyday EL34 made today. I like the JJ E34L better in most cases. If you are interested in 6L6 tubes, allow me give you my STRONGEST recommendation to go with Sovtek KT66. They have a KILLER tone, and easily best ANY 6L6 currently in production. Whenever I turn a guitar person onto these tubes(they are the big 6L6 users these days), they ALWAYS remark that they think they just bought a better amp. And, if I do the work for them, they swear I upgraded their amp in some way.
Opinions of Electro-Harmonix tubes?
Anyone try tubes from Electro-Harmonix? Would like opinions of their tubes (especially those of 6L6EH Power tube). How do their tubes compare with Svetlana or Sovtek power tubes? Thanks for the opinions. Their stuff seems reasonably priced and their claims are that they are just as good as current stuff or NOS in alot of cases.
