These tubes are both providing a smooth and well balanced tone which is a little bit uncharacteristically for “Made in China” tubes. They can be used in guitar/bass amps as well as in audio and HiFi tube amps. They will do a good job in both types of amps where 12AU7 and 12AT7 tubes are needed.

Often 12AT7 and 12AU7 tubes are used in stages which are designed for 12AX7 tubes. This is either to reduce the “maximum power” of the amp or just to make make the preamp a little bit gently. The biggest difference in sound will get attained with the 12AU7 instead of a 12AX7 – but at the end it is a question of taste.

Tube-Town 12AX7 Preamp-Tube - Balanced (Gain)

The TT12AX7 is a real 12AX7A China - today mostley only available as expansieve NOS tube.

This tube comes with well belanced highs and a high gain rate of about 110 Mu and low hum and background noise achieved with a modern manufacturing plant.
We recommend this tube for Clean, Crunch an Metal and similar sounds where hi-gain, low noise and an open ending is needed. We do not recomend this tube for Blues or if you need more mids... it might be to much for this !

Tube-Town 5881

High Grade Version of the 6L6GC tubes. Smooth and sweet Sound, long base ! Great replacement for all Fender Amps.

Good looking - better sounding. The heart and soul of Rock'n Roll - a great tube for amps which need a little extra kick !

This tube works great in classic amp-designs and layouts with a low complexity and a natural tube-sound. In suchs amps this tube produces a smooth, warme and well balanced, vintage-like sound.
We do not recommend this tube for the use in modern HiGain-Amps or in Phaseinverter stages. This is because of how the tube works. Tho we placed it into the family of 12AX7 tubes it is not a real 12AX7 / 7025 tube. The TT 7025 draws much less current if used with static 12AX7 parameters but - just like the 5751 which draws much more current than a 12AX7 - the TT 7025 works great in all 12AX7 stages due to the fact that these stages are mostyl auto-biased so the tube gets biased automaticly to its best operation point.

Der Austausch der Röhren in der Vorstufe kann in der Regel schnell und problemlos und ohne zusätzliche Einstellarbeiten durchgeführt werden. Bei den Röhren in der Endstufe ist dies oftmals leider nicht so einfach möglich.
Sofern der Verstärker über kein Auto-Bias (Kathoden-Bias oder ähnliches verfügt) muss nach dem Austausch der Röhren der Arbeitspunkt geprüft und möglicherweise neu eingestellt werden. Dies ist zwar kein grosser Aufwand aber nicht jeder Besitzer eines Röhrenverstärkers besitzt auch die hierfür notwendigen Messgeräte oder verfügt über das notwendige Wissen um die Einstellung selbst vor zu nehmen. Hinzu kommt, dass man unter Umständen mit Hochspannung in Berührung kommen kann und das bedeutet immer: Lebensgefahr. Daher besser den Verstärker zu einem Techniker bringen, der sich mit der Thematik auskennt ! Aber wo ist ein Techniker zu finden, der in meiner Nähe wohnt, die Arbeiten ausführen kann und normale Preise für die Einstellung verlangt ?
Alles nicht ganz einfach und vor dieser Problematik stehen viele unserer Kunden. Eine Lösung für das Problem bietet der Tube-Town Matching Service !
