I bought this as a backup for the Tung Sol already in the Demeter pre I just sold. It's never been out of the box.
And now for the science bit:
[i]Re-Issue Tung-sol 12ax7, now manufactured by Electro Harmonix at the reflector factory in Russia. The Tung-sol 12ax7 tube they produce is of high standard. With balanced triods and low microphonics makes it a good choice in all pre-amp stages including the V1 position. We highly recommend these tubes The Ultimate 12AX7. Big, warm, and musical. High Gain, ultra-low microphonics, and superb linearity with a dynamic 3-D sound. [/i]
Looking for [b]£12, posted 1st class [/b]in a jiffy with some extra bubble wrap.
Cheers
