Russian made reissue of the original Tungsol. The Ultimate 12AX7. Big, warm, and musical. High Gain, ultra-low microphonics, and superb linearity with a dynamic 3-D sound. Available with gold pins.

The Tube Amp Doctor premium selected 12AX7 / ECC83-Cz features big, warm, clean sounds with a mellow top-end when pushed to overdrive. It’s a great choice for guitar amps and HiFi alike. The ECC83-Cz is recommended if you want to emphasize punchy mids and is especially great when pushed into a fat overdrive. The TAD™ ECC83-Cz is a miniature, high-mu twin triode with good gain, round deep bass, somewhat compressed mids and very smooth top end. Selected and recommended for guitar amps to smoothen up the tone or for HiFi to shape the body of sound more to “that” tube tone. Best for jazzy and thick clean as well as for vintage bass response. Recommended for all positions in amps with medium gain level or High-Gain Amps for V2+ positions. As for V1 in general but especially for higher gain amps or phono/audio-amps, we recommend the RT030 7025/E83CC Highgrade, T-7025-HG-TAD.

Dissimilar double triode in the 9-pin miniature construction. It is especially suitable for applications requiring a high gain voltage amplifier and a cathodyne type phase-inverter.

The TAD ECC81 / 12AT7-Cz is selected with regards to a tight balance of both triodes making it ideal for the use as a balanced phase inverter. 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. Q: When does a power tube become a Premium Selected power tube? A: All power tubes labeled Premium Selected have passed the following tests:

• Plate Current (PC) and Amplification (TC)
• Low Noise Test
• Microphonic Test
• Sonic Tests
• Shock Tests
• Listening Tests
• Shorts & Leakage Tests

The new Tube Amp Doctor premium selected 12AX7 /ECC83-WA is a low-noise and low microphonic version of the 12AX7. The ECC83-WA Premium Selected has a balanced tone with a notable emphasis of the mids. The overall linear sound offers great string attack and chord separation. The low end is well defined. The result is a tone that works well in both modern amps but also vintage guitar amplifiers. If the ECC83-WA is used in hi-fi audio amplifiers, the tube adds a musical clarity and presence to the signal. The new TAD™ ECC83-WA is a miniature, high-mu twin triode, selected and recommended for guitar amps to improve overall responsiveness and dynamics. Great for guitar clean tones with a distinct pick attack and pronounced upper mids to cut through every mix. Crunchy tones still feature a very good string separation which is also ideal for fully saturated sounds and modern amplifiers with a tight bass response.
