NOS NIB TELEFUNKEN ecc88 6dj8 e88cc SEALED !!!

Here's something a bit special that I don't often propose. 
This NOS NIB Telefunken ecc88 is still in its sealed box and has never been opened. 
I usually prefer to open the few sealed box I had, so to be able to test the tube. But because I've been asked a few time for unopened sealed box NOs NIB tubes, I decided to proposed this one for sale.  Of course you can buy this buy and if you want I can carefully open the box and test the tube. I would provide then photos of the opening process and tests datas. But in that case please don't cancel the sale if the tests results doesn't fully suits you.

This sale is of course no return not knowing myself wich exact model, of wich year ...etc is in this box. So you can have the surprise of a rare version.
This sale is for collector, tube lovers and users wanting a never opened sealed box Telefunken ecc88 only. 

If you want  fully tested tubes see my other listings or just ask if you don't see what you're looking for.
This is a super  rare oportunity to get such a valuable collector intem in the same time as one the best ecc88 ever made !

Private sale so no guarantee or return please.

But if any problem (never happened yet ) please contact me first.

Thank you for your interest.
