My Brain Hurts

I was wondering the same thing. That might be the lowest profile PCB tube socket method I've seen before the turning the card sideways on a daughter board. 

For shipping it is easy to wrap a short length of bubble wrap around the tube and instruct the end user to remove it before plugging in the module.

It's not my idea. I saw it used on another project here ages ago and asked how they did it.

Don't use bubble wrap around the outside of new products though - it stains some paints

I didn't know that. Useful info. Thanks.

Cheers
