“After trying the Tung Sol 12AX7 also with cryo, my ears begged me to go back to the combo I had enjoyed with the previously use Mullard tubes. Now well broken in they have that smooth sound the whole family loves. As always great service I received them the next business day. Thanks Kevin and team.”
