Tubes for Shindo Aurieges L


I open my shindo aurieges l to check what kind of tubes it uses but the tubes doesn't have any markings on it. Does anybody know what kind of tubes for this preamp? Any tube recommendation?

I have tried several brands of NOS tubes in my Shindo Monbrison and they all had different characters. So why don't tube roll and be delighted to "taste" the differences between the different tubes. In a good system it should rather be fun than stress, at least with a Shindo amp.
Note ECL86 and LCP86 and are NOT interchangable. The advice posted above is WRONG. The ECL86 is no substitute and doesn't work in the current Aurieges.
how are you supposed to tell when things need retubing?  Have a used montille and got a demo unit aurieges.  sound fantastic but unknown hours on the tubes.  Tho if they are good to 10,000 then i guess they last a long time.
