The Bugera 12AX7A Preamp Tube features ultra-low noise, warmth and distortion for power stage preamplifiers. Product Highlights
| These are the gold pin version of the standard ECC83. These tubes are immediately discerni-ble from other 12AX7. They have a construction that is similar to a frame-grid tube - similar to the Telefunken ECC803s. This construction makes them very rugged and reliable. This is one of the best new 12AX7 for any guitar amp. It is very musical - rich with great harmonics. An excellent tube in all Marshall amps in the three preamp positions. Factory selected tubes with gold pins. These tubes provide high gain without the usual noise and microphonic problems you would expect. This is great sound and value for your money. ECC83S is 12AX7 high gain pre-amplifying double triode. Thanks to its design it also peforms with very low noise and microphonics. Harmonically rich, with a detailed low end and a warm high end. 12AX7/ECC83/7025 / 9Pin Socket Noval | DescriptionNN095-Electro Harmonix 12AX7 / ECC83 Vacuum tube 12AX7ЕН, 12AX7SV is a miniature twin triode with equipotential cathodes, designed to amplify low frequency voltage in radio engineering devices. 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.
| 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. Country of origin: Russia | 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.
