    Country of origin: China

    • Groove Tubes Silver Series are tested and warranted to meet or exceed factory specifications.
    • Silver Series tubes are excellent for "normal" tube replacement applications and offer exceptional value.
    • Not recommended for the critical high gain V1 stages of high gain guitar amps, but perfect for the other less critical stages such as V2-V6 stages.

        Comments about Groove Tubes Silver Series ST-12AU7-C Preamp Tube:

        The Silver Series ST-12AU7-C tubes work very well. I used them to replace 12AX7 tubes in my Hot Rod Deluxe. Only problem with that swap is that it reduced the output far too much. Should have gone with the 12AU7 tubes instead. But that is my own doings. I will still use this purchase.
