I have seen this in the ET3 as well as the ET5. In both cases putting in another tube (either JJ 6922 or even better Gold Lion 6922) took care of the problem.
As a general rule, avoid EH 6922 that have the 2010 date on them.

Tubes is the ET5 should last 3-5 year without a problem.
Most of my spare ones 411are 07 09. Replacement gat two are 09 09
