Hi, I bought a new Little Dot I+ and it works fine connected to a Musiland 02 DAC with a Van Den Hul D 102 MK III interconnect. I noticed one tube shines more than the other tube down at its base. I pushed down both tubes as hard as I can in its place and still one tube looks to be put deeper in its place than the other tube which sticks out. Is it a problem? How to fix it?
 

 
Thanks.
