hum is ok. the shut down is probably due to the unstable power. do you have any power conditioner with voltmeter so you can trace fluctuations?

I agree with the other commentators that you need to make sure the power is good. I would definitely try with a good power conditioner (and voltage regulator).
Also, has the unit ever been exposed to too much electricity such as a lightning storm. On conradjohnsonowners.com there was a story of a person who had electrical damage done to his CJ unit due to a storm and it was unrepairable. Perhaps something like this may have happened that damaged the electronics, perhaps in the on/off circuit if that is the problem your having?
I would probably give Ed a call at Conrad Johnson, he is very helpful.
Hi, thanks for the quick reply. Sorry for repeating the thread: I thought the first post hadn't gone through.
So far I haven't replaced the tubes. I am sure it is about time, but the issue has appeared very soon.
I am not sure about the a/c delivery here in Paris, but I guess it should not be that bad. I don't have a power conditioner. I am not sure it is linked to the power though: the troubke has gotten worst while the power is probably stable... After a temporary fix by a local shop which did not last more than two years, the issue started to appear again and became more an more frequent. I tried to earth the box with no results.
I thought it might be some electrostatic effect... Can it be?
I will send a mail to CJ. I guess they will ask to contact the local shop here...
