Remove the front locking edge of the inner jack by a file.(red arrow)
 

 
 
When remove this edge.The inner jack can insert into the outer body from the distal end.
This point is the very important because this work all part will insert from the distal end.
 

 
 
In the picture...now it can insert from distal end.

Thanks FraGGleR.
Panel mount is more easier,not to modify the rear part for solder.

But the face of panel mount is rectangle... 10x13 mm.

The face of board mount is square... 11x11 mm.

I use the board mount because the face shape is more matching
with the round bottom of Viablue.That I think it more beautiful. :)

I have now been so fortunate that I have got my very own Komkrit adapter, by cortesy of my friend Komkrit.

I would like to share a few words on how much I like this little beauty. It looks as if made in the Viablue factory, and the convenience of having such a compact adapter will allow me to balance all my future headphone cables. Currently I have only my lcd cable running on balanced, and now I can use that reference cable on any rig without a lot of hassle. This has also allowed me to finally evaluate my Intruder when running balanced or se. I must say the sq of the adapter seems really good, later hopefully I will have more cables so I can experiment more on the actual sq performance. So far I am thrilled!:)

Thanks Komkrit!
