My Jolida Glass Fx Tube DAC has 2 x 12AX7 valves. I see that the one valve "glows" quite a lot brighter than the other. Does this mean that one of them is on its way out?
My second question is what would you recommend as a replacement / upgrade from the standard Tung Sol tubes and where is the best place to source them. Thanks
