      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.
