QUAD FOUR Electro-Harmonix NEW 7025 7025EH Tube

Description

New QUAD (Four) Electro-Harmonix 7025EH tubes.  Here is factory info:
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.
This new production Electro-Harmonix tube is manufactured at their Xpo-Pul factory (also known as Reflektor) in Saratov, Russia.
It is a high gain, low noise valve with a short plate structure for reduced microphonics. Excellent for use in high gain Marshall pre-amplifier circuits where noise and microphonics can be a problem.
They are all recent date codes.
All tubes carry the 90 day factory warranty against defects from date of purchase.
I have been selling tubes of all types for more than ten years.  Buy with confidence.
