We test and match our tubes while under the stress of actual operating conditions, to the tightest, most demanding specifications in the industry with our proprietary aerospace-designed tube analysis system called Robotube. Only the absolute FINEST tubes are excepted. And then, as evidence, are backed with the best warranty in the business for a minimum of six months!

Please note: It isn't uncommon for a grid leakage indication to appear when testing EL34s in certain tube testers. This does not indicate a failed condition for a guitar amplifier. Not all tube testers test for parameters relevant to a tube guitar amplifier.
