Has anyone positively identified the tubes that ship in the Senn HEV90?

It’s been established that it uses Siemens tubes- 2X ECC83 (could they be E83CC?) and 4X ECL86.

If anyone owns the HEV90 and would do me a huge favor by checking the tubes I’d be forever grateful. At a minimum I’d like the get the acid etched tube codes of all the tubes. A picture of the individual tubes would be icing on the cake.


I ask because there are 6 or more permutations of the Siemens ECC83 \ E83CC and I’ve never heard anyone identify the specific tube used.


Thanks Mitch

Please take a moment from listening to the amp, remove the tube covers and enlighten us?

Being the tubes contribute so much to the sound I'm amazed no one was curious enough to investigate this issue.

Ditto. Someone please post!
