Single tube, not matched

Rugged and wonderful-sounding Power Beam tetrode that performs flawlessly at up to 475 volts. Great replacement for single-ended amps such as Fender Champ, or high plate voltage amps like the Fender Deluxe Reverb.

• Specially developed cathode coating
• Tri-alloy plate material
• Carefully aligned grid

TT Selection: Balanced
Both systems with balanced gain

• The 12AX7EH provides high gain with ultra low noise and detailed, musical tone that rivals the most desirable NOS types.

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.

TT Selection: V1 - Low Noise

Upgrade kit for the PoS100 with the following enhancements:     

• Selection of the adjustment range (Range): this effects the resolution of the load potentiometer. High initial damping allows easier fine tuning of the final volume. With a lower basic attenuation the adjustment range is wider and covers a larger volume spectrum     
• Selection of the control behavior (Log/Lin): depending on the amplifier, the control behavior of the load potentiometer can be adapted     
• The upgrade kit includes all components needed to update an existing PoS100 with these new features     

Please note: the schematic and layout plan for this kit will be sent by email together with the invoice, usually on the same day the order is sent.
