Hi Folks:
I purchased a pair of KenRad 6L6G for the regulator position in my Syrah, but one of the tubes does not appear to show any filiment lighting up and it's cold to the touch even after extended use (whereas the other one is lit up and warm/hot). I'm thinking the tube is dead but I've no equipment to test it. I got the tubes on eBay and they were listed as NOS but were untested. I'm wondering is my thinking right (is the tube definitely dead)? The strange thing is the music plays just fine, but then I tried removing the dead regulator tube to see how the music sounds, and it still sounds fine. Hence, I'm wondering what role these tubes play at all??? Any opions are welcome. Thanks.
