Genalex 12AX7 / ECC83 Reissue - BALANCED
NEW
TT Selection: Balanced
Both systems with similar gain


Original Genalex Gold Lion ECC83/B759 tubes are considered among the best 12AX7 types ever made. They are hard to find and when they are available, they are expensive. They exhibit a large detailed soundstage that is sought after by discerning audiophiles who demand the highest quality sound. The reissue Genalex Gold Lion ECC83/B759 recreates the sound signature of the original.
To be labeled Genalex Gold Lion, tubes must endure and pass the toughest testing the industry offers.

TT E83CC (12AX7 / ECC83 / 7025) - V1
TOP

TT Selection: V1 - Low Noise
This tube is selected for sensitive input stages (V1)


Tube-Town E83CC Preamp-Tube

High-quality 12AX7 / ECC83 / 7025 preamp tube with low background noise and reduced feedback tendency due to short anode plates, as well as a powerful bass and a dense sound. Very suitable for input stages with high amplification or amplifiers with generally high gain.
Dropin replacement for all 12AX7, ECC83, 7025, and E83CC tubes.

Electrical Characteristics

  • Heater voltage (Uf): 6.3V or 12.6V
  • Heater current (If): 300mA at 6.3V, 150mA at 12.6V
  • Anode voltage (Ua): Maximum 300V
  • Grid voltages (Ug1): -2V (typical)
  • Grid voltages: -50V to 0V
  • Anode current (Ia): 1.2mA (typical)
  • Anode power dissipation: Maximum 1W per triode
  • Anode resistance (ra): 62.5kΩ
  • Amplification factor (μ): 100
  • Transconductance (S): 1.6mA/V
  • Input capacitance (Cin): 1.6pF
  • Output capacitance (Cout): 1.6pF

Mechanical Characteristics

  • Socket: B9A (Noval)
  • Number of pins: 9

Pin Configuration

  • 1 Anode (Triode 1)
  • 2 Grid (Triode 1)

EH 7025  (12AX7 / ECC83 HQ) - Balanced
TOP

TT Selection: Balanced
Both systems with balanced gain

Electro-Harmonix has released a low noise, low microphonic version of the 12AX7 that meets all specifications required for the tube to be designated 7025. The original 7025 tube was a 12AX7 that was tested and selected for the lowest noise and microphonics for use in the critical first preamp stages of amplifiers where noise and microphonics could be an issue. In order to ensure that the 7025 specification is consistently met, Electro-Harmonix has redesigned the structure of the 12AX7 and has implemented construction techniques to ensure the absolute lowest noise and microphonics possible. In all samples tested, noise and microphonics could not be detected.

The Electro-Harmonix 7025EH has a mid-range that gives clarity and definition to the sound and a smooth top end for warmth and balance. With these characteristics, along with the exceptionally low noise and low microphonics, the Electro-Harmonix 7025EH will work equally well in vintage and modern high-gain guitar amplifiers, as well as sensitive phono preamps.
