Hi,
I just got your product: Little Dot MKIV Mk4 SE WE403AX2 6H30PIX2 Headphone Tube Amplifier + Pre-Amplifier.

Here is My order # 100015933.

When I check it, I find that the two large tubes are not located at the center, they almost directly contact the protecting rings, less than 1mmm, I think. I can send you those pictures. Please tell me how to do so if it's necessary?

My concerns are:
Could you please tell me whether it will damage the tubes when or after I plug in and turn it on?

and whether it will have any bad effects regarding the heat emission and lifespan of these two big tubes?
and most importantly, will this cause any bad effects on this MK 4SE amplifier for reaching its full function?

Currently, I do not dare to plug it in and turn it on till I get your kindly professional reply.

Thank you very much for your reply.
