Description

NN095-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.

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: RussiaThe Bugera 5U4 Rectifier Preamp Tube delivers the unique distortion, tone and warmth associated with the coveted Rectifier guitar amplifier. The 5U4 is ideal for both medium and high powered amplifiers due to its low heat dispersion. The tube easily replaces any tubes installed in Bugera guitar amplifiers. Product Highlights
  • Replacement Tube For Bugera Amplifiers
  • Ideal for Medium and High Power Amps
  • Low Heat Dispersion

6L6GC-STR Redbase RCA-Style TAD PREMIUM Matched Selected RT102 6L6GC-STR PAIR mactched Redbase TAD PREMIUM Selected 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.
