| The TAD JJ EL34 Quartett Matched Tubes
The JJ Electronic EL34 is another classic from JJ.
This tube features a rugged construction leading to an incredibly reliable EL34 with astonishing tone.
Overall the sound is nicely balanced with tight lows, a rich and dynamic mid range and clear highs.
The JJ EL34 is a great replacement for guitar amplifiers and stereo amps.

Top choice for gutiar / bass amp application with all the right ingredients. Excellent tonal bal-ance, harmonic content, low noise floor, and low microphonics. The tone is more vintage sounding, and also does very well in audiophile application. The 12AX7-EH tube has a nice balanced sound, a very low noise floor and excellent perfor-mance in terms of microphonics. The lack of microphonics is due in part to the return of a shorter plate structure and better materials.
| 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. Country of origin: Russia | Electro Harmonix EL34 EH Matched Pair(MP) Made In Russia 1 Pair matched vacuum from the excellent "Black base" pentode of high power. Perfect EL34 for vintage equipment and to improve the performance of modern amplifiers. Excellent music with a rich, smooth and detailed sound. Tube Type EL34/6CA7/E34L Socket: Octal(8pin) | Product information "ECC81 / 12AT7-Cz TAD Premium Selected (balanced)"
The TAD ECC81 / 12AT7-Cz is selected with regards to a tight balance of both triodes making it ideal for the use as BALANCED PHASE DRIVER. In addition to the perfect symmetrical systems, the strong amplification characteristics of the TAD ECC81 / 12AT7-Cz support increased dynamics of the output stage when used as phase driver or phase inverter tube.
All preamp tubes labeled Premium Selected have passed the following tests:
- Low Noise Test
- Microphonic Test
- Gain Test
- Sonic Tests
- Shock Tests
- Listening Tests
- Balanced Output Test
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.
