Tube damper sir? I do believe that what you need is the *slight tapper.*
I switched the tube from the right channel to the left and haven't had an issue since. I'll have my "slight tapper" at the ready though.
That might be the pins. Might need to clean and restraighten. And then retention the socket.
@Azimuth I cleaned the pins with Deoxit before installing them the first time. I'll check for slightly bent pins if I have any more issues. Thanks for the tips.
It might be from your tube socket then to tighten up those pins. Just bend them from the sides to the middle.
