Content | The Bugera EL84-4 Pack Power Amp tubes are subject to rigorous quality tests such as a 48-hour burn-in test and their vibration table test. The EL84 is the most common low power pentode tube, popularized in early Vox AC30 amps. Delivers quick, soft overdrive distortion, great for recording but usually too low volume for live gigs. | GROOVE TUBES GT 12AT7 PREAMP TUBE
The Groove Tubes GT-12AT7 preamp tube is manufactured to the highest quality JAN spec. NOS, made in Russia for extremely long life.
Used widely in most U.S.-made amps and, in particular, Fender amps. Fender amps with reverb use 2 - 12AT7s -- one for the reverb drive stage, and one as a phase inverter to drive the push/pull output stage. The makeup of the 12AT7 is very similar to the 12AX7 and it can be substituted for a 12AX7 in a pinch. Some players prefer the 12AT7 in the driver stage of a Marshall for a cleaner, brighter tone. (The driver or phase inverter is the 12AX7 located nearest the power tubes.) The 12AT7 is rarely used in a tone-generating stage, but rather in function stages, so the Groove Tubes GT-12AT7 is selected for durability.

Really a versatile tube.

Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems.
This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.
