    So I brought my jcm slash in for a pre amp tube change since the pre amp tubes is what was causing my amp to lose a little bit of its gain. I had some bs pre amp tubes in there. Today I went to Sam ash and bought the groove tubes 12ax7c. They're made in China and I heard the Chinese tubes are made for more the high gain amps. What do you guys think??

    I think that is a good choice of preamp tube. I have the silver jubilee reissue and use the shuguang 12ax7 which I believe is what your groove tubes 12ax7c. Just relabeled. It sounds quite fine in these amps. Also tung Sol are a nice choice for a 12ax7.
