| Content | 6L6GC designed for incredibly sparkly clean tones. One thing all Bugara Tubes have in common is the airtight quality control they must undergo before they fall into your hands. When we say hand-selected, were talking about an actual person individually testing each BUGERA valve. Tone means everything because it means everything to you, and we take every measure to make sure our tubes really give your sound the soul of valves. | 12AU7 / ECC82.
A lower-gain substitute for the 12AX7/7025 preamp tube. Good for a cleaner, quieter sound.
Electro-Harmonix sound effects are world renown for the soulful warmth of their analog sound and their line of "EH" premium tubes continues in this tradition of classic tone. | 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.

Matching and Selecting Options for Preamp Tubes
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.
TAD Premium Selected/Highgrade tubes are guaranteed for a period of 6 months (according to terms of warranties)
for the quality criteria mentioned above.

The Classic 6L6 Sound - Excellent Tone and Maximum Lifetime!
The TAD 6L6GCM-STR REDBASE is a latest 6L6GC designed and built to claim to be the best 6L6 type tube ever manufactured.
A damn high claim, but we are sure that we have achieved exactly that.
In terms of sound, the TAD 6L6GCM-STR REDBASE produces the powerful but always defined bass response known from the legendary american built NOS RCA 6L6GC, with clear, unobtrusive and yet transparent highs. In every setting, the TAD 6L6GCM-STR REDBASE responds directly and with noticeable dynamics, from buttery soft and warm to powerful and brutal without losing any details or depth.
This makes the TAD 6L6GCM-STR an effective upgrade for every amplifier using 6L6GC or 5881 tubes; also repalces any EL37, CV586, VT115A, 6L6GA, 6L6GB, 6L6WGB, 6L6WGC, STR-440, STR-454, 6p3p, 6p3s, 6p3s-e etc.
The TAD 6L6GCM-STR REDBASE combines the structural advantages of the robust American Philips / Sylvania 6L6GC, also known as MESA 6L6GC-STR415, and the sound quality of the legendary RCA 6L6GC tubes.
Silky highs, defined, deep bass and lots of headroom recommend the TAD 6L6GCM-STR REDBASE for lively clean sounds as well as a powerful broadband power amplifier for multi-channel amps.
