Audio Aero Capitole - 6021W subminiature tube ??

I would appreciate hearing from someone who can explain the performance of these tubes in the Capitole, including the typical life of the tubes, whether they are susceptible to becomming microphonic or noisy, and how to purchase or change them if necessary. I believe I read these are really small (like the diameter of a pencil) and that they are soldered onto the board. If that is true, is it then necessary to send the player back to the distributor or manufacturer if they need replaced, or are these readily available and set up for user installation? How many years is typical for the tubes to perform in the Capitole before replacement is necessary? Thanks.

What was wrong, good question... nobody knows.
After months of fruitless repairs, appeared that he did not like my Legrand Power Strip to which my Audio Magic Eclipse was connected, AA was connected to Eclipse. I had to connect Eclipse to power strip which do not have any reactive elements, just the cheapest, simplest one I could buy. My AA is very finicky when it comes to power supply. It works from one socket at home and do not from another. I know it sounds crazy. I have asked electronics engineer about that, he was flabbergasted and could not explain it seeing it by himself.
Important now it works.

I get Sylvania's in Finland:
http://vacuum-tube-shop.com/. Have sent them for cryo treatment to: http://cryoset.com/ (really cheap).

Do you know if in SE upgrade Philips or Sylvania 6021 W are used ?

I have the AA Cap Reference SE and my tubes are Philips, this does not mean the Philips sound better than the Sylvania, I think the Sylvania are just in short supply. I got some Sylvanias from Vacuum-Shop and another source from that part of the world. I contacted Tube World about getting mine Cryo treated but I'm just not sure it's worth it, Like I said, I think the Cryo might have been part of the selling point of the SE upgrade.

Soldering 6021wa tubes into the circuit.
Audio aero tubes are soldered in with short leads and
the tubes in vertical position.
this may lead to some microphonics problems.
personally i keep the leeds lonng and bent the wires so the tube are iin an horizontal position more or less floating position.
I can give you some tubes for trial.
good luck
