Tung Sol 5751 Top Quality lower gain pre-amp valve

Excellent Tung Sol 5751 valve  made in Russia, and a godsend for people needing  a top quality 5751 pre-amp valve.
Please note on the 5751:
Sometimes a 5751 can be used in place of a 12AX7/ECC83. Some folks  that have gear that come equipped with 12AX7’s will substitute  a 5751. They do this specifically because it colours the sound and changes the way the amp performs, as they look for ways to “distort.” This is a matter of taste as the 5751 is a lower gain tube than the 12AX7/ ECC83S . If someone tells you to use a 5751 because they like it, make sure it’s the same piece of gear. A lower gain valve can, depending on the circuit, operate perfectly. However, in some extreme cases, the lower gain can cause high distortion and in some cases not even work properly. The 5751 has a different biasing point to an ECC83/12AX7 type
We have tested these top quality valves and each has a sticker on the box showing the anode current when tested with 250 volts on the anodes and -2 volts bias. We test them on our quality AVO valve testers.
A good alternative is the EH 7025 which is more  compatible with ECC83 and 12AX7 types
We also stock the JJ Electronic 5751 and the EH7025
