Audio Aero Capitole MK II: Performance & Problems

Thanks for the response, Lwatson! If the heater remains on, couldn't that also fail prematurely due to it's constant 'on' state in standby? Or, in other words, does the 10,000 hours of tube life refer to 10,000 hours of actual use (ie, while actualy listening to the unit)?

Tube life / Replacement Question -Capitole MK II.
I've owned my MKII for about a month now, with zero problems, and I love it. But I have a question. I notice, that when I have the unit in Standby, the tubes are still on. The expected tube life is 10,000 hours (roughly 14 months). Shouldn't the tubes be off in standby to preserve tube life? If the answer is to shut off the whole player - wouldn't it would take many hours to warm-up the player again from a cold start?
If a tube goes bad, how do you replace it? Isn't it hard wired into the circuit (ie, no tube socket)? And, no, I am not a technician, so I wouldn't trust myself with a soldering iron in my hands, working on a piece that retails for $8700 (U.S.). Anyone got any knowledge / advise? (Oh, and one last thing, I have no local dealer to go to).

Lall: I don't know who Mr. Combelles is (perhaps you could let me know), however, I have emailed Darrell (above - he says he is the guy who services Audio Aero), and here is his response:

If you plan to not use the unit for a week or more definitely turn it off. As far as the tube life, they should really last at least 2 years. I've only had to replace one tube in a MK1 and that tube had a slight hum in it, otherwise there have been no others that needed a tube replaced.
I don't recommend trying to replace a tube yourself because if you don't do it carefully you can damage: the tube, the pc board, and melt wires.

So, it appears that the tube is soldered (I understand that this was not the case with the original Capitole, ie pre 24/192)and, as Darrell states, he does not 'recommend trying to replace a tube yourself'. It seems to me that this should have been covered in the owner's manual.
I have emailed him back asking where I should send the unit for tube replacement. When I hear back, I will post an update.
