New gold pin Genalex 12AX7 ECC83 B759 with matched and balanced sections when needed for sensitive circuit locations such as the V1 Phase Splitter. This is arguably the finest current production 12AX7 available and hard to find at a reasonable price.
This new production Genalex 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 the highest quality audio amplifiers/pre-amplifiers.
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.
