I can't see how you can blame the eh tubes as I have not had these issues with my art/prem 16 in the past.

Anyone else had any tube noise issues?
I have confirmed with CJ that there was a defective series of tube from EH. It appears the 2010 series of 6922 have had a high failure rate with many going noisy only after a few hundred hours.
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.
