Highly sought after audio tube. NOS 7025 tested on a Mercury 1000 Mutual Conductance tube tester at 100% on both sides.
The 7025 is a premium dual-triode vacuum tube originally designed as a low-noise, low-microphonic version of the standard 12AX7A. Famous for its use in historic George A. Philbrick Researches (GAP/R) analog computing equipment and high-end audio, it can be directly replaced by any modern 12AX7 or ECC83.
George A. Philbrick Researches (GAP/R) utilized 7025, 12AX7, and 6BR8 tubes in their pioneering vacuum tube operational amplifiers (such as the K2-XA and K2-W). These analog computing modules relied on the 7025's high-gain and low-noise characteristics to process electrical signals for industrial control systems and early computing.
The above quotes were harvested with the help of AI. This is an excellent tube to use in position 1 for preamps in high gain amps.
Shipping to USA 48 states ONLY. No returns or refunds so please be sure you want the tube before you buy.
Thanks for looking and best of luck!
