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! Testing and Matching capacity is where confidence and true value come in. In the case of any MESA tube, you can install with complete confidence of guaranteed premium performance from the world’s leading designer of custom, hand-wired amplifiers.

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.
